4. A woman pushes a stroller with a force of 8.2 N and performs 28.7 J of work on the stroller. Over what distance was the
Force applied?

Answer:
3.5m
Explanation:
Given parameters:
Force applied = 8.2N
Work done = 28.7J
Unknown:
Distance through which the force was applied = ?
Solution:
Work done is the force applied on body to move it through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
28.7 = 8.2 x distance
distance = 3.5m
