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
P = 160 watts.
