Use this formula to solve this problem: Power (P) = Work (W) ÷ time (t) Joachim's body supplies a force of 450 N to run up a 20 meter hill in 15 seconds. How much power is involved in Joachim's run up the hill? A. 22.5 Watts B. 30 Watts C. 600 Watts D. 300 Watts
The answer is C. When solving this problem, we also need another formula: Work=Force*Distance. With this formula, we can get the work of Joachim in this process is 450*20. According to the first formula, the Power=450*20/15=600 Watts
