-20. Two cyclists, Mike and Josh, simultaneously started toward each other from two towns d = 24 km apart. Josh rode at vj = 25 km/h, and Mike %3D at UM = 15 km/h. The moment they start, a fly also starts from Josh towards Mike and after reaching Mike, immediately returns towards Josh. The fly continues back and forth motion between the cyclists till the cyclists meet. Air speed of fly is UF = 30 km/h and the wind blows always towards Mike with a constant velocity u = 10 km/h. Find the total distance s flown by the fly. Sneedometer shows speed and odometer shows distance travelled, both
How would you find the velocity (and direction) of the cue ball after the collision? (answers are 2.58m/s at 45.1° South of East but I'm not sure on how to get those answers)
I was standing on the side of a 10-m foot bridge, holding a ball while watching a car approaching the bridge at uniform speed. When the car was 15 meters away from where I was standing, the ball thatI was holding slipped in my hand and the car arrived at the bridge when the ball hit the ground. What was the speed of the Car ? (Assume that the final velocity of the ball is NOT zero)
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.
An outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in the figure, but that the ball's speed after the bounce is one-half of what it was before the bounce. 0 O 0 (a) Assuming the ball is always thrown with the same initial speed, at what angle should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 45.0° with no bounce (green path)? (b) Determine the ratio of the time interval for the one-bounce throw to the flight time for the no-bounce throw. tone-bounce tno-bounce
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?
2) notation, what is its velocity 0.5 s later it is shot? (g = -9.8ĵ m/s²) ; A ball is shot from the roof of a building into the air with a velocity i = (2î + 3f) m/s. In unit vector Answer: ở = (2î – 1.9j) m/s %3D
