Practice Questions

Question 1

A rocket in deep space expels exhaust gases at a high velocity. Which principle primarily explains the rocket's propulsion?

Question 2

A billiard ball moving at a certain velocity collides with an identical stationary billiard ball. After the collision, the first ball comes to a complete stop, and the second ball moves off with the initial velocity of the first ball. What type of collision is this?

Question 3

A system consists of two objects, A and B. Object A has a mass of $m$ and velocity of $v$. Object B has a mass of $2m$ and velocity of $-v/2$. If they undergo a perfectly inelastic collision, what is the final velocity of the combined mass?

Question 4

A car of mass $M$ is traveling at a velocity $V$ when it collides head-on with a stationary truck of mass $2M$. If the collision is perfectly inelastic, what percentage of the initial kinetic energy is lost during the collision?

Question 5

An object experiences an impulse of $J$. If the force causing this impulse was quadrupled and the time duration of the force was halved, what would be the new impulse experienced by the object?
