$20 \times 5 = 100$

Answer 2

Answer:

Power used by Samarth is 49 Watt.

Step-by-step explanation:

m = 20 kg

h = 5 m

t = 20 s

Force = m * g

=> F = 20 * 9.8

=> F = 196 N

Now,

W = F * s

=> W = 196 * 5

=> W = 980 J

Now,

Power = Work/Time

=> P = 980/20

=> P = 49 Watt

Power used by Samarth is 49 Watt.
