7. CALCULATE: How much work is done in each of the following examples? Show all of your
calculations.
a. A child uses 4 N of force to pull a wagon a
distance of 2 m along a sidewalk.
b. A construction worker uses 30 N of force
to drag a toolbox a distance of 3 m

a. 8J

b. 90J

W = F × s

W = Work done (J)

F = Force (N)

s = distance (m)

a. F = 4N

s = 2m

b. F = 30N

s = 3m

a. W = ..?

b. W = ..?

a. W = F × s

= 4N × 2m = 8J

b. W = F × s

= 30N × 3m = 90J
