A Cambra pouce car traveling at 28 m/s slow at a rate of at 3.6 m/s every second find.
a) The time taken for the police car to come to Stop?​

t = 7.8 seconds

Explanation:

Given that,

The initial speed of the car, u = 28 m/s

Acceleration of the car, a = 3.6 m/s²

We need to find the time taken for the police car to come to Stop. When it stops, its final speed is equal to 0. So, using the equation of kinematics to find it i.e.

So, the required time is 7.8 seconds.
