Question1

A rocket is fired at a speed of 87.0 m/s from ground level, at an angle of 50.0 ° above the horizontal. The rocket is fired toward a 29.0-m high wall that is located 37.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall?

Question2

A cyclist starts from rest and the accelerates for 20 seconds. He then travels at a constant speed for 1 minute and finally accelerates at 2 m/s2 until he stops.

Part A. Find out his maximum speed

Part B. total distance travelled

Question3

A square thin of side (a) and mass (m) is thrown into the air that it rotational period =1 sec if the axis of rotation make 45 with the symmetry axis of the plate .find the precession period of the axis of rotation about symmetry axis. Also find out the angle between (w) and (L)
