Linear Momentum MCQ - Practice Questions with Answers

A ball of mass $0.20kg$ hits a wall at an angle of ${45}^{\circ }$ with a velocity of $25\mathrm{m}/\mathrm{s}$. If the ball rebounds at ${90}^{\circ }$ to the direction of incidence with the same speed. Calculate the magnitude of change in momentum of the ball.

A ball is thrown vertically up (taken as + z-axis) from the ground . The correct momentum -height (p-h) diagram is :

A bullet of mass 10 g moving horizontal with a velocity of 400 m s^-1 strikes a wood block of mass 2 kg which is suspended by light inextensible string of length 5 m. As result, the centre of gravity of the block found to rise a vertical distance of 10 cm. The speed of the bullet after it emerges out horizontally from the block will be

A ball of mass 0.15 kg is dropped from a height 10 m. strikes to the ground and rebounded to the same height. The magnitude of impulse imparted to the ball is ( $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ ) nearly:

A stone is dropped from a height of h. It hits the ground with a certain momentum P. If the same stone is dropped from a height 100% more than the previous height, the momentum when it hits the ground will change by:
