Question

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?

Answer 1

A aceleração do carrinho é de, aproximadamente, 1,46 m/s².

Step-by-step explanation:

F=ma

F: force

m: mass

a: aceleration

66 = 45a

a=66/45= 22/15 ≅ 1,4666 m/s²

Answer 2

`a=1.46\ m/s^2`

Step-by-step 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

`a=(F)/(m)`

`a=(66\ N)/(45\ kg)`

`a=1.46\ m/s^2`

So, the acceleration of the cart is
`1.46\ m/s^2`. Hence, this is the required solution.
