What is the value of work done on an object when a 50-newton force moves it 15 meters in the same direction as the force?
The answer is 7.5 10² J
A work (W) is a product of a force (F) and a
distance (d):
W = F · d
It is known:
F = 50 N
d = 15 m
W = ?
So, let's just substitute the parameters:
W = 50 N 15 m = 750 Nm = 750 J = 7.5 10² J
