Question

A force of 67 newtons pushes a shopping cart so that its kinetic energy increases by 300 joules. how far does the cart go while it is being pushed?

A) 2.39 meters
B) 4.48 meters
C) 6.22 meters
D) 8.96 meters

Answer 1

The cart goes approximately 4.48 meters while being pushed.

Step-by-step explanation:

To find the distance the cart goes while being pushed, we can use the work-energy principle. The work done on an object is equal to the change in its kinetic energy. In this case, the force pushing the cart is 67 N and the change in kinetic energy is 300 J. We can use the formula:

Work = Force × Distance

Rearranging the formula, we have:

Distance = Work / Force

Plugging in the values, we get:

Distance = 300 J / 67 N ≈ 4.48 meters

Therefore, the cart goes approximately 4.48 meters while being pushed. So the correct answer is B) 4.48 meters.
