Laws of Motion — NEET PYQ

A block of mass 10 kg is placed on a rough horizontal surface (μ = 0.3). The minimum force required to just move the block is: (g = 10 m/s²)

A lift accelerates upward at 2 m/s². The apparent weight of a 50 kg person inside is: (g = 10 m/s²)

A body of mass 5 kg is acted upon by a force F = (3i + 4j) N. The acceleration of the body is:

Two masses 5 kg and 3 kg are connected by a string over a frictionless pulley. The acceleration of the system is: (g = 10 m/s²)

A body of mass 2 kg has momentum 10 kg⋅m/s. Its kinetic energy is:

A gun of mass 4 kg fires a bullet of mass 50 g at 100 m/s. The recoil velocity of the gun is:

A car of mass 1000 kg is moving at 20 m/s. The braking force needed to stop it in 10 s is:

Impulse is equal to:

Coefficient of friction depends on:

On a banked road of angle θ, the maximum safe speed for a car without friction is:
