A1400-kg car is traveling with a speed of 17.7 m/s. what is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 33.1 m?

The magnitude of the horizontal net force is 13244 N.

Explanation:

Given that,

Mass of car = 1400 kg

Speed = 17.7 m/s

Distance = 33.1 m

We need to calculate the acceleration

Using equation of motion

Where, u = initial velocity

v = final velocity

s = distance

Put the value in the equation

Negative sign shows the deceleration.

We need to calculate the net force

Using newton's formula

Negative sign shows the force is opposite the direction of the motion.

The magnitude of the force is

Hence,  The magnitude of the horizontal net force is 13244 N.

0.11 m/s and 0.28 m/s should be correct
