The diagram below depicts two cases in which a 0.2 kg ball strikes falls
and strikes the ground. Case A: the ball is moving downward at 5 m/s
when it hits the ground then rebounds upward at 2 m/s. Case B: The ball
moving downward at 5 m/s when it hits the ground and stops
immediately. Calculate the momentum change of the ball for each case.
Then, explain which ball, if any, experiences the greater force. Show all of
your work."

scientific laws are the result of testing theories and proving them to be facts.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
