Question

A car is moving with a velocity of 40 ms-1. The driver sees a
stationary truck ahead at a distance of 200 m. After some reaction
time At the breaks are applied producing a (reaction) retardation of
8 ms-2. What is the maximum reaction time to avoid collision?​

Answer 1

Step-by-step explanation:

The car before coming to rest (v=0) <br>

<br>

<br> The distance travelled by the car is

<br> To avoid the clash, the remaining distance

must be covered by the car with uniform velocity

during the reaction time

. <br>

<br> The maximum reaction time
