Sample Questions
A stone is tied to a string of length 1 m and whirled in a vertical circle. The minimum velocity at the lowest point to complete the circle is: (g = 10 m/s²)
A force of 10 N acts on a body of mass 2 kg for 3 s, imparting an impulse. The change in velocity of the body is:
Two masses M₁ = 5 kg and M₂ = 3 kg are connected by a light string passing over a smooth pulley. The system is released from rest. The acceleration of the system and the tension in the string are respectively: (g = 10 m/s²)
A bullet of mass 10 g moving at 300 m/s strikes a sandbag and penetrates 5 cm before stopping. The average resistive force is:
A car of mass 1000 kg moves on a circular track of radius 40 m. If the coefficient of friction between the tyres and the road is 0.6, the maximum speed with which the car can move without skidding is (g = 10 m/s²):
Two bodies of masses 4 kg and 6 kg are tied to the ends of a massless string passing over a massless pulley. The acceleration of the system due to gravity is: (g = 10 m/s²)
A block slides down an inclined plane at 30° to the horizontal. If the coefficient of kinetic friction is 0.2, the acceleration of the block down the plane is: (g = 10 m/s², sin 30° = 0.5, cos 30° = 0.866)
A body of mass m is rotating in a vertical circle. The difference between the tensions at the lowest and highest points is:
