bonnie pulls a cart that weighs 195 N with a force of 18.0 N. According to Newton's 3rd law, with what force does the cart pull back on bonnie

The force exerted by the cart on Bonnie is - 18.0 N

Explanation:

Given;

weight of the cart, w = 195 N

Bonnie's applied force on the cart, F = 18.0 N

According to Newton's 3rd law, action and reaction are equal and opposite.

Thus, the cart will pull back at Bonnie with force of equal magnitude but in opposite direction.

The force exerted by the cart on Bonnie = - 18.0 N
