A ball hits a floor and rebounds after an inelastic collision. In this case,
a) Total energy of the ball and the earth remains the same
b) Total momentum of the ball and the earth is conserved
c) Momentum of the ball just after the collision is same as that just before the collision
d) Mechanical energy of the ball remains the same during the collision
a) Total energy of the ball and the earth remains the same
b) Total momentum of the ball and the earth is conserved
c) Momentum of the ball just after the collision is same as that just before the collision
d) Mechanical energy of the ball remains the same during the collision
View answer and explanation
Correct option: C
a, b
Option C is correct because in an inelastic collision, the total energy of the ball and earth remains the same, and the total momentum of the ball and earth is conserved.

A ball throwing cannon, lifts ball and throws with Speed. If balls are raised upto . then find Input power of cannon if it lifts 8 balls per minute and its efficiency is . Mass of each ball is .
Assertion:When a particle moves in a circle with a uniform speed its acceleration is constant but the velocity changes.
Reason: Angular displacement is not an axial vector. A body of mass thrown vertically upwards attains a maximum height . As what height will its kinetic energy be of its initial value? Assertion: Centripetal force does no work.
Reason: Force and displacement are perpendicular to each other. Statement I: Both stretched and compressed springs possess potential energy.
Statement II: Work done against restoring force is stored as potential energy. A bullet of mass moving at a speed hits a ball of mass kept at rest. A small part having mass breaks from the ball and sticks to the bullet. The remaining ball is found to move at a speed in the direction of the bullet. Find the velocity of the bullet after the collision.
