Explanation:
Given parameters:
Weight of Ben = 600N
Weight of Dan = 600N
Distance of pull-up = 0.5m
Unknown:
Work done by each pull - up = ?
Solution:
Work done is defined as the product of the force applied to move a body through a certain distance.
Work done = Force x distance
Work done by Ben And Dan will be the same:
Work done = 600 x 0.3 = 180J
Work done by Ben = 180J
Work done by Dan = 180J
