Answer 1

Answer:

Power = Force × velocity (if both are vectors, take rhe dot product)

Assuming she is on earth and gravity is 9.8 m/s²,

(20 kg x 9.8 m/s²) × (5 m/20 s) = 196 N × 0.25 m/s = 49 W

This ignores the power exerted to carry herself up the 5 m, and is commonly how tractors, locomotives, etc. are rated.
