Suppose a hammer of mass 1 kg is falling freely on the wooden block, if the hammer fall from a height of 1 m. How much kinetic energy just before hitting the wooden block?

A 2 kg ball is dropped from a height of 1. Find its kinetic energy just before hitting ground.

A body of mass 5 kg is dropped form a height o 1 m. Its kinetic energy just before reaching the ground is

How much momentum will a dumb-bell of mass 10 kg transfer to the floor if it falls from a height of 80 cm ? Take its downward acceleration to be 10 ms ^(-2) .

A bullet of mass m fired at 30^@ to the horizontal leaves the barrel of the gun with a velocity v. The bullet hits a soft target at a height h above the ground while it is moving downward and emerges out with half the kinetic energy it had before hitting the targtet. which of the following statements are correct in respect of bullet after it emerges out of the target?

An inclined plane making an angle of 30^@ with the horizontal is placed in a uniform horizontal electric of 100 V m^-1 as shown in the figure A particle of mass 1 kg and charge 0.01 C is allowed to slide down from rest from a height of 1 m. If the coefficient of frictio nis 0.2, find the time it will take the particle to reach the bottom.

A body losses half of its velocity while penetrating 3 cm into a wooden block, then how much will it penetrate ore before coming to rest?
