Explanation:
Answer:
160 watts.
Explanation:
Remark
Power = Work / Time
Work = F * d
Note: Since he is running up stairs he is doing work against gravity.
Givens
- m = 50000 g kg / 1000 grms
- m = 50000 / 1000 = 50 kg
- h = 4 m
- time = 12.5 seconds
- g = 10 m/s^2
Formula
- P = W * d/t
- W = m*g *d / t
Solution
- P = 50kg * 10 m/s^2 * 4 m / 12.5
- <em><u>P = 160 watts. </u></em>

Answer:
because its not going down a long hill instead its going on a leveled street
R is the distance from the center of the Earth to the object in orbit. So, the object isfalling<span> towards the Earth, but just keeps missing the Earth.
