Question

Newton’s 2nd Law: F=ma. If you push a shopping cart with 130 N of force, and it accelerates at 3 m/s², what is the mass of the cart?

Answer 1

43.3kg

Step-by-step explanation:

Given parameters:

Force = 130N

Acceleration = 3m/s²

Unknown:

Mass of cart = ?

Solution:

From Newton's second law of motion:

F = m x a

F is the force on the body

m is the mass

a is the acceleration

So;

m =
`(F)/(a)` =
`(130)/(3)` = 43.3kg
