Question

A 1,200 kg car is accelerated at 3.7 m/s2. What force was needed to produce this acceleration?

Answer 1

The answer would be A

Answer 2

Answer:

A. 4,440 N

Explanation:

A Force applied on an object with mass 'm' can change its velocity in a unit time. This change is called acceleration.

If a force 'F' is applied on a body of mass 'm', it produces an acceleration 'a' in the body.

Force is give as :

F = ma

In our case,

m = 1200 kg    a = 3.7 m/s²

F = 1200 x 3.7

F = 4440 kgm/s²

F = 4440 N
