If a body loses half of its velocity on penetrating 3 cm in a wooden block, then how much will it penetrate more before coming to rest (in cm)?

Which physical quantity is represented by the ratio of momentum and velocity of the body?

A car has an initial velocity of 12 m/s and is brought to rest over a distance of 45 m. The acceleration of the car is

A car weighs 1000 kg. It is moving with a uniform velocity of 72 km/h towards a straight road. The driver suddenly presses the brakes. The car stops in 0.2s. The retarding force applied on the car to…

The ratio of kinetic energies of two bodies of same mass is 4 : 9, the ratio of their velocities will be

If the linear momentum of a moving object gets doubled due to application of a force, then its kinetic energy will
