Question

a box is pushed 40 m by a mover. the amount of work done was 2,240j. how much force was exerted on the box a box is pushed 40 m by a mover. the amount of work done was 2,240j. how much force was exerted on the box @Physics

Answer 1

Answer:

F= 56 N

Explanation:

Work theory

Work is the product of a force applied to a body and the displacement of the body in the direction of this force.

W= F*d Formula (1)

W: Work (Joules) (J)

F: force applied (N)

d=displacement of the body (m)

The work is positive (W+) if the force goes in the same direction of movement.

The work is negative (W-)if the force goes in the opposite direction to the movement

Data

W==2240 J

d= 40m

Problem development

We apply the formula (1)

W= F*d

2240J= F* 40m

F = 2240 N*m / 40m

F= 56 N

Answer 2

Use equation, force×distance=work done(a form of energy).
force=work done÷distance= 2240÷40=56N
