Asked by Hammad
A force of 5.0 N acts on a 15 kg body initially at rest. Compute the work done by the force in (a) the first,(b) the second, and (c) the third seconds and (d) the instantaneous power due to the force at the end of the third second.

I'm guessing we're ignoring friction.
a = F/m
v = at
and KE = Work = 1/2mv^2
for part d) P = W/t
a = F/m
