At a certain factory, 340 kg crates are dropped vertically from a packing machine onto a conveyor belt moving at 1.00 m/s. (a motor maintains the belt's constant speed.) the coefficient of kinetic friction between belt and crate is 0.400. after a short time, slipping between the belt and the crate ceases and the crate then moves along with the belt. consider the period of time during which the crate is being brought to rest relative to the belt.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
