A basketball player grabbing a rebound jumps 70 cm vertically.
How much (total) time does the player spend in the top 25 cm of this jump?
How much (total) time does the player spend in the bottom 25 cm of this jump?

What are the relevant equations? What is your attempt at solving this?
 
WOW thanks for helping
 
You aren't going to be given an answer without showing that you've tried, and you definitely aren't going to be given an answer for being rude.

Have some hints:
a = -9.81 m/s/s
s (displacement) = 0.70 m
v at peak of jump = 0 m/s

use constant acceleration formulae.
