Question

A car on flat ground accelerates at 0.785 m/s2 when a net force of 1050 N acts on it. How much normal force acts on it?

Answer 1

13108 works as well for acellus

Answer 2

13108.3N

Step-by-step explanation:

Given parameters:

Acceleration = 0.785m/s²

Net force = 1050N

Unknown:

Normal force acting on car = ?

Solution:

The normal force on this car is the weight of the car;

Normal force = mg

where m is the mass of the car

g is the acceleration due to gravity = 9.8m/s²

Now solve for the mass;

Net force = mass x acceleration

1050 = mass x 0.785

mass =
`(1050)/(0.785)` = 1337.6kg

So,

Normal force = 1337.6kg x 9.8m/s² = 13108.3N
