Answer:

The work done in pushing the cart is 3500 J

Explanation:

In this problem, we are to solve the work done in pushing the cart. To do this, we need to get the product of the pushing force to the distance it has traveled.

Formula to use

W = F·d

where

W     is the work, the unit is in Newton-meter (N·m) or Joules (J)

F      is the force, the unit is in Newton (N)

d      is the distance, the unit is in meter (m)

Given information

F = 500 N

d = 7 m

W = ?

Solving the problem

Let us solve the work using the given formula

W = F·d

Then, substitute the given data

W = (500N)(7m)

W = 3500 N·m or

W = 3500 J

Therefore, the work done in pushing the cart is 3500 J.
