Question

2

You give a shopping cart a shove down the aisle. The cart is full of groceries and has a mass of
30 kg. The cart accelerates at a rate of 2 m/s^2. How much force did you exert on the cart? *
(2 points)
60N
15N
120N
30N

Answer 1

60 N.

Step-by-step explanation:

From the question given above, the following data were obtained:

Mass (m) = 30 kg

Acceleration (a) = 2 m/s²

Force (F) =..?

Force is simply defined as the product of mass and acceleration. Mathematically, it is expressed as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can calculate the force exerted on the cart as follow:

Mass (m) = 30 kg

Acceleration (a) = 2 m/s²

Force (F) =..?

F = ma

F = 30 × 2

F = 60 N

Therefore, a force of 60 N was applied to the cart.
