What is teminal velocity?
A student of mass m=50kg runs an experiment. He throws a ball of mass m = 400g from a height h = 20m. What will be the speed of the ball he records just before it touches the ground?
Explain what the terminal velocity of an object is.
A ball of mass 1kg is rolled down a hill of height 10m. At the bottom it collides with another ball of mass 5kg. What speed does the second ball move away with? You can assume the collision between the balls is elastic.
