Respuesta :

The net force of the cart when it is pushed to the right with a force of 15N.

Explanation:

To find the force of net, which is calculated by the  formula.

The Net Force= Addition of the force applied on the respective  direction.

The Net Force here is given by

The Net Force = 15-20 (A force towards the right and a force towards left, two opposite so subtraction).

Hence

Thus the Net Force = -5(The force towards left, so it gets a  negative value).
