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?
A car starts from rest and moves along a straight line with an acceleration of a = (3s -1/3) m/s2, where s is in meters. Resolve the car's velocity and position when t = 10 s.
A 200g ball on a 60 {cm}-long string is swung in a vertical circle about a point 200 {cm} above the floor.

A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
Find an average magnitude of the induced emf . A bungee jumper, who's mass is 79 kg, jumps from a tall building. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.2 s.
A car is traveling 17 m/s when the driver sees a child standing on the road. He takes 0.8 s to react, then steps on the brakes and slows at 7.5 m/s2. How far does the car go before it stops.
