Question

A truck accelerates 2 m/s2 when it is empty. If the truck is filled so that it has twice the mass and the same amount of net force is applied, how much will the truck accelerate?

8 m/s2
1 m/s2
4 m/s2
2 m/s2

Answer 1

This is a conceptual problem, I’ll try to upload a picture:

Answer 2

Answer :

a = 1 m/s^2

Explanation:

Given information

Net force is a constant

The mass of the truck is $m_{o}$

Initial acceleration $a_{o}$= 2 m/$s^{2}$

The mass of the truck is increased twice as much

$F_{net}= m_{o} a_{o}$ = ma

$F_{net}= m_{o} a_{o}$ = $2m_{o}$a

a=$\frac{a_{o} } {2}$

a = 2/2

a = 1 m/$s^{2}$
