When one person launched a model rocket straight upwards, it will accelerate at 3.7g(g=9.81m/s^2) for 4.1 seconds. Then the rocket will burn out(ignore air friction).What is the maximum height the rocket will reach? And what will the time from launch until it returns to the ground?

Yahya throws a ball at a height of y, = 2 m above ground with an initial speed of v, = 8.8 m/s at an angle of e, = 40° with respect to the vertical direction. [Recommended time : 6-8 minutes] A 6m high vertical wall stands 4 m away from Yahya. Will the ball go over the wall without hitting it? Oa. Yes Ob. No Oc. Maybe Od. You did not give enough information

A ball is suspended from a light 1.3 m string . The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)?  What will be the maximum angle, in degrees, the string will make with the vertical?

A rock is thrown straight up into the air with an initial speed of 85 m/s at time  t = 0.  Ignore air resistance in this problem. At what times does it move with a speed of 13 m/s? Note: There are two answers to this problem.
