Q.
A hollow sphere of mass m = 1 kg and radius R = 1 m rests on a smooth horizontal surface. A simple pendulum having string of length R and bob of mass m = 1 kg hangs from top most point of the sphere as shown in the figure. A bullet of mass m = 1 kg and velocity v = 2 m/s partially penetrates the left side of the sphere. The velocity of the sphere just after collision with bullet is:
1 m/s
0.5 m/s
1.5 m/s
2 m/s
Q. A block of mass M=5 kg is moving on a horizontal plane. An object of mass m=1 kg is dropped on to the block hitting it with a vertical velocity of v1=10 m/s. The speed of the block at the same instant is v2=2 m/s along the floor. The collision is momentary and the object sticks to the block upon collision. What will be the speed of the block just after the collision if the co-efficient of friction between the block and the horizontal plane is 0.4.
- 0.8 m/s
- 1.67 m/s
- 1.4 m/s
- 1 m/s
