The length of nylon rope from which a mountain climber is suspended has a force constant of 1.40×10^{4} 4 n/m . (a) what is the frequency at which he bounces, given his mass plus and the mass of his equipment are 90.0 kg? (b) how much would this rope stretch to break the climber's fall if he free- falls 2.00 m before the rope runs out of slack? hint: use conservation of energy.

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?

An automobile steering wheel is shown. what is the ideal mechanical advantage? if the ama is 8, what is the efficiency of the steering wheel?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
