1. The problem statement, all variables and given/known data A 1200 kg car accelerates from 0 to 27 m/s in 60 seconds. a) What is the power outage from the engine in watts? b) What is the power outage from the engine in horsepower? 2. Relevant equations 1/2 mgy=v 1 horsepower=746 Watts 3. The attempt at a solution My final answer was 2025 Watts, 2.71 horsepower. Either I am way off, or my physics teacher is testing my confidence with physics. I'm guessing the former. a) v=1/2(1200kg)(4.5m/s)2=12150 Joules=2025 Watts. 2025 Watts/746=2.71 horsepower. Where did I go so terribly wrong?? :rofl: Thanks!
