What is Physics Problems on Motion and Forces about?
1. A football is stopped by a player in 1/50 seconds, bouncing back at 15 m/s. The average force on the ball is 500 N. 2. A rocket accelerating upward at 20 m/s^2 needs 127.5 kg/s of exhaust ejected at 800 m/s to provide the necessary thrust. 3. When a stone is dropped from a height 100% greater than the original, its momentum upon impact increases by 100%.
