Q. A 1.50 kg box (position is given in meters and time is given in seconds) slides on ice for 1.5 seconds and then encounters a rough surface. Find out the momentum at the start of the animation. Is momentum conserved during the first 1.5 seconds? Is momentum conserved during the next three seconds?

A flower pot and a basketball collide with the table (position is given in meters and time is given in seconds). Each has the exact same mass. Which object undergoes the greater change in momentum after colliding with the floor? Which object undergoes the greater change in kinetic energy after colliding with the floor? Is force of the floor on the flower pot greater or less than the force of the floor on the basketball?
