A person tossed a headball up at an initial rate of movement of 15 m / s, and it rose and fell, and that person met it again. Find 1. How high does the ball reach? 2. What was her speed at the moment prior to being caught 3. How much time did the ball spend in the air?

A tether ball of mass m is attached to a vertical pole by a rope of length L. Determine the angle the rope makes with the pole (0) as an implicit function of the speed of the ball (v), m, L, and g. Free-Body Diagram Mathematical Analysis Questions If the mass of the ball was twice as large, what would happen to ? Ifv = 0 m/s, what should e equal? Does your function agree with this observation? Ifv = 0, what should e equal? Does your function agree with this observation?

A happy kangaroo leaps vertically upward at a time t = 0. At time t = 0.50 s the kangaroo is at a height of 2.0 meters above the ground. What is the speed and direction of motion of the kangaroo at this time (at t = 0.50 s)? Neglect air friction. 4.9 m/s downward 1.55 m/s upward O none of these 2.45 m/s downward 4.9 m/s upward 2.45 m/s upward

A helicopter with a mass of 10,000 kg takes off straight up at t=0. The thrust of the engine is defined given as a function of time: FT= 95 0.18t- (kN). Where t is in units of seconds. How fast is it rising and what is its elevation at t=4s?

Sweden and Norway are at war over who makes the best pickled herring. You are in charge of a Swedish artillery unit that is trying to shoot at some Norwegians located 1000 meters away at the same height as you are. If we neglect the friction of the air, the cannon ball follows a parabolic trajectory; as you certainly recall from prior courses, a cannon ball travels a distance L = V²sin(2a) 9 where V is the initial velocity, a is the angle of the cannon barrel, and g = 9.8 m/s² is the gravitational acceleration. You realize that you only have two options for how to shoot. Option (I) is to use 1 bag of gun powder, which produces an initial velocity of exactly V₁ = 105 m/s, and to try to set the angle to aI,nominal = 39 degree. Option (II) is to use 2 bags of gun powder, which produces exactly VII = 137 m/s, and to try to set the angle to aII,nominal = 15 degree. If you set the angles exactly to the nominal ones, compute the traveling distances. L₁ = LII = The problem is that the cannon…

Learning Goal: A particle of mass M moves along a straight line with initial speed v₁. A force of magnitude F pushes the particle a distance s along the direction of its motion. 99°F Sunny

Please write legibly.

can you pls also draw a picture/representation of the scenario described? Thanks so much!

A rocketship has 9 modules each with a mass of 15 200 kg and moves at a speed of 7.0 km/s. One of the modules is explosively propelled away from the rocketship at a speed of 1350 km/h with respect to the rocketship, opposite in direction from the original travel direction of the rocket ship.What is the resulting change in the speed of the rocketship?

Please answer question 2. Thank you!
