An alpha-particle of mass m suffers 1-dimentinal elastic collision with a nucleus at rest of unknown mass. It is scattered directly backwards losing 64% of its initial kinetic energy. The mass of the nucleus is : A body of mass m=10−2kg is moving in a medium and experiences a frictional force F=−KV^2. Its initial speed [...]
A piece of wood of mass 0.03 kg is dropped from the top of a building 100 m high. At the same time, a bullet of mass 0.02 kg is fired vertically upward with a velocity of 100 m/s from the ground the bullet gets embedded in the wooded piece after striking. find the height to which the combination rises above the building before it starts falling take g=10m/s^2

A particle of mass m is moving with speed 2v and collides with a mass 2m moving with speed v in the same direction. After collision the first mass is stopped completely while the second one splits into two particles each of mass m which move at angle 45^° with respect to the original direction. The speed of each of the moving particle will be
