1. The problem statement, all variables and given/known data A weightlifter is able to lift 250 kg 2.00m, in 2.00s. What is his power output? 2. Relevant equations W=M x N P = W/Change t 3. The attempt at a solution 250 x 2 = 500 (I thought that this was work) so then I divided by time (2.00s) to get power. The answer is not right. It should be 2.45 kW. Please tell me what I am doing wrong.
