So here's my hw problem: Calculate KE of a 1500 kg vehicle moving at 30 m/2. Which I did, and got 675000 joules, using the standard KE formula. But then it asks, if the vehicle accelerated to this speed in 20 seconds, what average power was developed? Any formula for power involves a distance, which is not given here at all. Can someone help me out? Is it a trick question?
