A force produces an acceleration of 5.0m/s2 when it acts on a body of mass 2 kg for 2 seconds. Find the work done by the force.
Given mass of body m = 2 kg
Initial velocity, v = 0 m/s (at rest initially)
time t = 2 sec
let the displacement in 2 sec be s
s = ut + 12at2 = 0 ×2+12×5×22 = 10 m
work done, w = force × displacement w = m ×a ×s = 2 kg ×5ms2× 10 m = 100 J
Hence work done by the Force will be 100 J
