2. a boy pushes forward a cart of groceries with a total mass of 45.0 kg. what is the
acceleration of the cart if the net force on the cart is 66.0 n?

Explanation:

It is given that,

Mass of the cart, m = 45 kg

Net force acting on the cart, F = 66 N

Let a is the acceleration of the cart with which it is pushed. It can be calculated using Newton's second law of motion as :

F = m a

So, the acceleration of the cart is . Hence, this is the required solution.

answer: b.

explanation:

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
