Question

Calculating Mass from Potential Energy A skier with a potential energy of 137,200 J waits on top of a ski jump that is 200 m high. What is the mass of the skier? 20 kg 70 kg

Answer 1

Answer:70k

Step-by-step explanation:

Answer 2

`Given:\\E_p=137200J\\g=9,8 (m)/(s^2) \\h=200m\\\\Find:\\m=?\\\\Solution:\\\\E_p=mgh\;\;\;/:gh\\\\m= (E_p)/(gh) \\\\m= (137200J)/(9,8 (m)/(s^2)\cdot 200m) =70kg`
