Question

if a 990 kg car is on the road and the Ff is 360 N, what is the normal force?

Answer 1

Hello,

To find the solution to this question use the normal force formula:

N = mg

Where,

N = normal force

m = weight 

g = acceleration of gravity

Therefore:

 N = (990 kg) x (9.80 m/s²) 

= 9702 N

Thus, the normal force of the car is 9702 N.

Answer 2

Explanation:

It is known that relation between normal force and mass is as follows.

                      N = m × g

where,    N = normal force

              m = mass of an object

              g = acceleration due to gravity = 9.8 $m/s^{2}$

And, it is given that mass of the car is 990 kg. Hence, calculate the normal force as follows.

                       N = m × g

                           = $990 kg \times 9.8 m/s^{2}$

                           = 9702 N

This force will be acting in the upward direction.

Thus, we can conclude that the normal force for given situation is 9702 N.
