Directions: Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls to the ground. Think about the amounts of potential and kinetic energy the bowling ball has: • as it sits on top of a building that is 40 meters tall.

• as it is half way through a fall off a building that is 40 meters tall and travelling 19.8 meters per second.

• as it is just about to hit the ground from a fall off a building that is 40 meters tall and travelling 28 meters per second.

1. Does the bowling ball have more potential energy or kinetic energy as it sits on top of the building? Why?

2. Does the bowling ball have more potential energy or kinetic energy as it is

3. Does the bowling ball have more potential energy or kinetic energy just before it hits the ground? Why?

4. What is the potential energy of the bowling ball as it sits on top of the building?

5. What is the potential energy of the ball as it is half way through the fall, 20 meters high?

6. What is the kinetic energy of the ball as it is half way through the fall?

7. What is the kinetic energy of the ball just before it hits the ground?

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
