Two friends are playing billiards at an arcade center. One guy hit the cue ball to strike at another ball where it is initially at rest. After the collision caused by the ball that was at rest, the cue ball moves at 2.50 m/s along a line making an angle e=14.0° with its original direction of motion and the second balI has a speed of 1.50 m/s. Find the answer for Part a,b and c. (Note: Both balls have the same mass.) Part A: Find the angle 0 between the direction of the motion of the second ball and the original direction of motion of the cue ball. Part B: Find the cue ball's original speed? Part C: Figure out whether kinetic energy is conserved?

people love to play with balls nowadays especially during quarantine as theres not much to do. lets say we have a ball that hits another ball that is at the rest. after they hit and smash each other, the first ball moves 4m/s on the platform and makes an angle of 25 degrees while the other ball has a speed of 3m/s.. FIND a)get the angle b3tween da d1rection of motion of da second one (ball) and the original direction of motion of da first one. b) find da original sp33d of the first one c)let me ask u this question. is the kinetic energy is being conserving?
Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
A shinobi threw a kunai due east at a velocity of 130 m/s relative to the shinobi. The shinobi was sprinting due east at 7.23 m/s relative to ground. A samurai used his bow to shoot a directly at an interception path. The arrow is due west. The samurai was stationary when the arrow was released. The velocity of the arrow due the direction of the kuna is 124 m/s relative to the samurai. The samurai and the shinobi were 147 meters away from each other. a. What is the velocity of the kuna relative to the arrow in kph? b. What is the time it will take for the kunai and arrow to be in contact? c. What is the distance of the contact point from the samurai?
Two particles are initially at the point (0,0) (the origin) of a coordinate system. Particle A moves along the positive r-axis with a speed of 2 m/s. Particle B moves along the positive y-axis with a speed of 3 m/s. 2. How fast is the distance between the two particles changing, when Particle A is 6 meters from the origin? Draw a diagram of the situation and label it. Answer with an exact value.
When a chronometer begins with a time of zero seconds, matching soccer balls have a horizontal separation, d=6.28m. The ball on the left is released from the ground with an initial velocity of magnitude v0 directed toward the other soccer ball. The ball on the right has an initial height h1=3.17m and is momentarily at rest. A short time later, the matching soccer balls collide at the collision point, C, at a height h2-1.69m above the ground, as indicated on the diagram. Ignore the finite size of the balls, and additionally ignore any air resistance. (Dimensions are not to scale.) Part (a) Given the numeric values in the problem statement, tabulate the elapsed time, in seconds, at which the matching soccer balls collide. Part (b) Given the numeric values in the problem statement, tabulate the magnitude, in meters per second, of the initial velocity of the soccer ball on the left.
A person throws a ball with speed 102 m/s at a 45° angle. How many seconds faster would the ball arrive if the person threw the ball at the same speed and the same distance but made the trip in two identical bumps. Assume that there is no loss of speed at the bounce. Hint: Use R = v2/g * sin(2θ) and t=2*vy(sinθ)/g.
Arugby player runs with the ball directly toward his opponent's goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball's velocity relative to the field does not have a positive × component. Suppose the player runs at speed 4.5 m/s relative to the field while he passes the ball with velocity O Bp relative to himself. If O Bp has magnitude 6.4 m/s, what is the smallest angle it can have (relative to the positive direction of the x axis) for the pass to be legal?
Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.30 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 52.5 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 9.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. I. With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? (Express your answer in meters per second.) II. Where is Henrietta when she catches the bagels? (Express your answer in meters.)
Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?
Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 3.90m/s, but from Pauli's point of view, Newton appears to be moving at 1.50 m/s due East. What must Pauli's velocity relative to Daniel be for this to be true? Express your answer in terms of the ? and ?‑components if North is the +? direction and East is the +? direction. a) ?-component (m/s): ?-component (m/s): b) Express your answer as a magnitude and an angle measured counter‑clockwise from due East.
