A lift ascends from rest with uniform acceleration of 4m/s², then it moves with uniform velocity and finally comes to rest with uniform retardation of 4m/s². If the total distance covered during ascending by the lift is 28m and the total time for ascending 8s respectively, then find the time for which the lift moves with uniform velocity. Also find its uniform velocity.
The Attempt at a Solution
I am trying to find the time for acceleration, retardation and uniform velocity separately by using equations of motion....but somehow I am not being able to solve it....the information looks inappropriate.
(The answer given is 4m/s)
