A lift performs the first part of ascent with uniform acceleration `a` and the remainder with uniform retardation `2a`. The lift starts from rest and finally comes to rest. If `t` is the time of ascent. Find the height ascended by lift.

A lift performs the first part of its ascent with uniform acceleration a and the remaining with uniform retardation 2a. If t is the time of ascent, find the depth of the shaft.

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

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 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))
