A lift is coming from 
floor and is just about to reach 
floor. Taking ground floor as
origin and positive direction upwards for all quantities, which one of the following is correct?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
When the lift reaches 
floor is about to stop hence, motion is retarding in nature. Hence,
.
As displacement is in negative direction, velocity will also be negative i.e., 
.
Ground floor is origin and lift is in up words direction so its position is
