Billy-Joe stands on the Talahatchee Bridge kicking stones into the water below. A. If Billy-Joe kicks a stone with a horizontal velocity of 3.5 m/s, and it lands in the water a horizontal distance of 5.4 m from where Billy-Joe is standing, what is the height of the bridge?
B. If the stone had been kicked harder, how would this affect the time it would take to fall?

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

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
