Question

Level 2
41. A lift ascends from rest with uniform acceleration of
4 m s-. Then it moves with uniform velocity and
finally comes to rest with a uniform retardation of 4
ms-2. If the total distance covered during ascending is
28 m and the total time for ascending 8 s, respectively,
then find the time for in which the lift moves with
uniform velocity. Also find its uniform velocity.
​

Answer 1

Answer:

A lift ascends from rest with uniform acceleration of 4m/s^2, then it moves with uniform velocity and finally comes to rest with uniform retardation of 4m/s^2. If the total distance covered during ascending is 28m and total time taken for ascending is 8s respectively.
