Answer: Work is 1.7 kJ, Power is 280 W
Explanation: Work W = mgh, power P= W/t
W = 85 kg·9.81m/s²·2 m = 1667.7 J
P = 1667.7 J / 6 s = 277.95 W
Answer:
Using Newton's law of gravity, we find that the force of earth's gravity on your body at the equator is 9.798 m/s2 times the mass of your body, whereas at the poles it is 9.863 m/s2 times the mass of your body.
