a) the initial momentum is 6 kg*m/s, and the final momentum is 3 kg*m/s
b) the initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s
c) the initial momentum is 12 kg*m/s, and the final momentum is 3 kg*m/s
d) the inital momentum is 6 kg*m/s, and the final momentum is 12 kg*m/s

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
