In the movie Back to the Future, Doc Brown and the young Marty McFly need 1.21 GW of power for their time machine. (a) Convert that power requirement to horsepower.
Added by Stephen W.
Step 1
1 GW = 1,000,000,000 W So, 1.21 GW = 1.21 * 1,000,000,000 = 1,210,000,000 W Show more…

In the movie Back to the Future, Doc Brown and the young Marty McFly need 1.21 GW of power for their time machine. (a) Convert that power requirement to horsepower. (b) If a stock DeLorean sports car produces 145 hp, how many times more power does the time machine need?

A solar racing car* typically has a power of about 1.2 kW (1.2 kilowatts). What is this in horsepower (hp)? (Use the conversion 1 hp = 745.7 watts). For practice, write your answer formally using the 'multiply by 1' technique we've been using. Give your final answer as a number, with the appropriate number of sig figs. Do NOT include units. 1.2 kW = _____ horsepower.
