A car starts from rest and travels with uniform acceleration a, for some time and then with uniform retardation `beta` and comes to rest. If the total time of car is 't', the maximum velocity attained by it is given by

A car starts from rest and travels with uniform acceleration prop , for same time and then with uniform retardation beta and comes to rest. The time of motion t. Find the maximum velocity attained by it, (alphabetat//(alpha+beta))

Starting from rest, a train traveIs a certain distance with a uniform acceleration alpha . Then it traveIs with a uniform retardation beta and finally comes to rest again. If the totaI time of motion is t,find (i) the maximum velocity attained and (ii) the totaI distance travelled by the train.

A car starting from rest, accelerates at a constant rate x for sometime after which it decelerates at a constant rate y to come to rest. If the total time elapsed is t, the maximum velocity attained by the car is given by

A car starts from rest and moves with uniform acceleration for time t then it moves with uniform speed of 60 km/h for time 3t and comes to rest. Find the average speed of car in its total journey.
