Question

A 1675 kilogram car is moving to the right at a constant velocity of 25m/s . what is the net force exerted on the car ? ​

Answer 1

Explanation:

Explanation:

Newton's first law states that an object in motion tends to stay in motion unless if acted upon by a net force. This means that if friction is not being accounted for, there is no net force required to keep an object moving if it's in motion. A net force is only required to change an object's motion. The 500 kg object is moving at a constant velocity; therefore, there is no net force (0 Newtons) acting on the object

Answer 2

Given:

1675 kg car is moving with constant velocity of 25 m/s.

To find:

Force exerted on the car ?

Calculation:

• The question clearly says that the car is moving with a constant velocity. That means the velocity is not changing with time.

• So, the acceleration (i.e. a = ∆v/∆t = 0) of the car is zero.

So, force experienced by car is :

$F = m \times a$

$\implies \: F = 1675 \times 0$

$\implies \: F =0 \: N$

So, net force exerted on car is 0 N.
