Question

A car accelerates from rest at a constant rate α for some time after which it decelerates at a constant speed β to come to rest. If the total time elapsed is ,, the maximum velocity acquired and total distance travelled by the car are given by

Answer 1

Correct Option (d)

Explanation:

Let the car accelerate for time t₁ travelling distance S₁ and acquiring maximum velocity v.

After this car decelerates for time t₂ to come to rest

Also, total distance travelled,
