A physics book of unknown mass is dropped from a height of 5m above the ground. (Use g = S 1.) What type of energy does the book have initially? Respond in the first text box. 2.) What type of energy does the book have just before it hits the ground? Respond in the second text box. 3.) What is the speed of the book just before it hits the ground? Show your solved equation in the math answer box (you should see a mathematical answer!) 4.) Write the units for your final answer in the last text box.

A kilowatt-hour (kWh) is a unit of measure equal to one thousand watts of electricity being used in one hour. Power companies use this measurement to determine your home energy bill. Consider using a bike for power: It takes 6 minutes pedalling at 24-26 volts consistently to produce just 1/10 (0.1) of a kWh. An average home uses about 25 kWh a day. How long would someone have to pedal at 24-26 Volts to power an average home?
