Question

A 2000 N net force will give a car with some amount of mass an acceleration of 4 m/s2

What acceleration will the same net force give a truck whose mass is twice that of the car?

Answer 1

2m/s²

Step-by-step explanation:

Given parameters:

Net force on the car = 2000N

Acceleration = 4m/s²

Unknown:

Acceleration of a car twice the mass = ?

Solution:

Let us first find the mass of the car;

Force = mass x acceleration

Mass =
`(Force )/(acceleration)`

Mass =
`(2000)/(4)` = 500kg

Now,

whose mass is twice that of the car

Mass of the new car = 2 x 500 = 1000kg

So;

Acceleration =
`(Net force )/(mass)`

Acceleration =
`(2000)/(1000)` = 2m/s²
