200m
40m
4m
400m
Correct answer is C
according to the work-energy theorem; Workdone = change in kinetic energy.
W = ∆ K.E
force x distance = \(K.E_2 - K.E_2\)
10 x s = 60 - 20
s = \(\frac{40}{10}\) = 4m.

1800 W
Correct answer is B
power = \(\frac{force * distance}{time}\) → \(\frac{200 * 9}{5}\)
power = 36w
