Question

A car accelerates from rest at a constant rate a constant rate b and comes to rest. If the total tume elapsed is t, the maximum velocity acquired by the car is​

Answer 1

Answer:

v= aB/a + B t

Explanation:

let maximum velocity = v

Now , v= 0 + at1

similarly 0 = v - Bt2

t1 = V /a & t2 = v/B

t1 + t2 = t = v/ a + v/ B

=> v = aB / a Bt
