Answer:
Explanation:
Equations
You need two equations.
P = W / delta time
W = F * d
Givens
F = 20 * 10N The 10 Newtons is what is important.
d = 30 m
t = 1/2 minute = 30 seconds
Solution
W = F * d
W = 20*10N * 30 m
W = 6000 Joules
Power
Power = Work/time
Power = 6000 joules / 30 seconds
Power = 200 watts
Note a watt is a Joule / second.
