You push a cart with a mass of 15kg, giving it an acceleration of 3

The force acting on the body, F = 45 N

Explanation:

Given,

The mass of the cart, m = 15 kg

The acceleration of the cart is, a = 3 m/s²

The force acting on the body is proportional to the mass and acceleration of the body.

The force formula,

F = m x a

Substituting the given values,

F = 15 kg X 3 m/s²

= 45 N

Hence, the force acting on the body, F = 45 N
