Question

A car accelerates from rest at a constant rate alpha for some time after which it decceletrates at a constant rate beta and comes to rest if the tootal time is t what is the total distance covered

Answer 1

Explanation:

Let maximum velocity=v

Now,v=0+αt

1

Similarly, 0=v−βt

From the above equations we get,
