Question

A car accelerates from rest at a constant rate alpha for some time after which it decelerates at a constant rate beta to come to rest. the total distance travelled is​

Answer 1

Answer:

Initial velocity (u) = 0; Acceleration in the first phase =

Deceleration in the second phase = and total time = t.

When car is accelerating then final velocity (v) or and when car is decelerating,

then final velocity

or .

Therefore total time (t) =

or
