An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

The car traveled the distance before stopping is 90 m.

Explanation:

Given that,

Mass of automobile = 2000 kg

speed = 30 m/s

Braking force = 10000 N

For, The acceleration is

Using newton's formula

Where, f = force

m= mass

a = acceleration

Put the value of F and m into the formula

Negative sing shows the braking force.

It shows the direction of force is opposite of the motion.

For the distance,

Using third equation of motion

Where, v= final velocity

u = initial velocity

a = acceleration

s = stopping distance of car

Put the value in the equation

Hence, The car traveled the distance before stopping is 90 m.
