A pendulum of mass m and length l is suspended from the ceiling of a trolley which has a constant acceleration a in the maximum deflection theta of the pendulum from the vertical.

The ring shown in fig. is given a constant horizontal acceleration (a_(0)=gsqrt(3)) . The maximum deflection of the string from the vertical is theta_(0) . Then

If trolley accelerates horizontally with acceleration a then bob is displaced backward from its initial vertical position. The angular deflection of the bob in equilibrium is

In the figure shown, find out acceleration of each block.

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. The maximum deflection of the thread with the vertical is

A shell of mass 1kg is projected with velocity 20m//s at an angle 60^@ with horizontal. It collides inelastically with a ball of mass 1kg which is suspended through a thread of length 1m . The other end of the thread is attached to the ceiling of a trolley of mass 4/3kg as shown in figure. Initially the trolley is stationary and it is free to move along horizontal rails wihtout any friction. What is the maximum deflection of the thread with vertical? String does not slack. Take g=10m//s^2 .

When the trolley show in figure is given a horizontal acceleration a , the pendulem bob of mass m gets deflected to a maximum deflection , the net acceleration of the bob with respect to trolley is

A ball of mass m = 1 kg is hung vertically by a thread of length 1=1.50 m . Upper end of the thread is attached to the ceiling of a trolley of mass M = 4kg . Initially, the trolley is stationary and it is free to move along horizontal rails with out friction. A shell of mass m=1 kg , moving horizontally with velocity v_(0) = 6m//s collides with thread starts to deflect towards right At the time a maximum deflection of the thread with vertical, the trolley will move with velocity
