Question

The door to the classroom weighs 3 kg. How much work is done when Michael pushes on

the door to the classroom with 15 Newtons of force, pushing the door 1.3 meters?

Answer 1

Work done : 19.5 J

Further explanation

Given

F = 15 N

d = 1.3 m

m = 3 kg

Required

Work done

Solution

Work is the product of force with the displacement of objects.

Can be formulated

W = F x d

W = Work, J, Nm

F = Force, N

d = distance, m

Input the value :

W = 15 N x 1.3 m

W = 19.5 J

the mass has no effect on this problem
