Consider a shell that has a muzzle velocity of 45ms^(-1) fired from the tail gun of an airplane moving horizontally with a velocity of 215 ms^(-1) . The tail gun can be directed at any angle with the vertical in the plane of motion of the airplane. The shell is fired when the plane is above point A on ground, and the plane is above point B on ground when the shell hits the ground. (Assume for simplicity that the Earth is flat)

A ball of mass in m= 1 kg is hung vertically by a thread of length l = 1.50 m . Upper end of the thread is attached to the ceiling of a trolley of mass M= 4 kg . Initially, the trolley is stationary and it is free to move along horizontal rails without friction. A shell of mass m=1 kg , moving horizontally with velocity v_(0 )= 6 m//s collides with the ball and gets stuck with it. As a result, the thread starts to deflect towards right. At the time of maximum deflection of the thread with vertical, the trolley will move with velocity
