Answer:
m=50 kg
t = 20 seconds
h= 16 /100 × 20 = 125
P = W/T
work done = mgh
Therefore , P = mgh/t = (50 × 10 × 125 ) / 20
= 62500 / 20 = 3125
hence the power is 3125

Answer:
the ans is 100 W
Explanation:
Mass = m = 50 kg
Total height = h = 25 x 16 = 400 cm = 400/100 m = 4 m
Time = t = 20 s
Power = P = ?
Power = work/time = w/t = mgh/t
P = 50*10*4/20
P = 100 W
