Question

A car starts from rest and accelerates with a uniform rate of Alpha for sometime and then starts deaccelerating with a uniform rate of Beta until it comes into rest if total time T for journey then find the total distance travelled by the car in total time interval ​

Answer 1

Answer:

Let maximum velocity=v

Now,v=0+αt

1

Similarly, 0=v−βt
