Finally, the water park at an amusement park has rides that are essentially this lab on a large scale. A 45 kg rider falls a total distance of 22.5 m for one of these, sliding down an incline of 31.5 degrees. If there were no friction, how long would the ride last (while they are in the tube?) How fast would they exit the tube in 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
