Question

A 1000 kg car is accelerated from rest to 100 miles/hour in 10 seconds. Find the output power of this car

Answer 1

Okay its like 98.8 or something...you have to convert miles per hour to meters per second. Then do

(1/2)(Mass)(velocity) that'll give you your kinetic energy (work). Divide that by time to get Power.
Remember, it gives you your answer in watts but Rawwaga's answers are in Kilowatts so divide by 1000. Whichever one is really close (not exact) is the right answer!
