Question

The brakes applied to a car produce an acceleration of 6 m/s2 in the opposite direction to the motion. If the car takes two seconds to stop after the application of brakes, calculate the distance, it travels during this time.​

Answer 1

Answer:

12 m

Explanation:

To calculate the displacement ( s ), we will first require the initial velocity of the car ( u ). Since, the car stopped after applying the brakes, the final velocity ( v ) is 0 m/s

Using

$v = u + at$

We get, u = 12 m/s ( Use a = -6 m/s^2 )

Now to get the displacement ( s ), we use,

$s = ut + \frac{1}{2} a {t}^{2}$

Working on it,

$s = 24 - 12 = 12 \: m$
