Physics question about finding the coefficient of kinetic friction!!! PLEASE HELP!!!!?

Question

A 24 kg crate initially at rest on a horizontal floor requires a 75 Newtons horizontal force to set it in motion. The coefficient of static friction between the crate and the floor is 0.32.
Once the crate is in motion, a horizontal force of 53 Newtons keeps the crate moving with a constant velocity. What is the coefficient of kinetic friction between the crate and floor??

PLEASE HELP ME!!!! THANKS IN ADVANCE!!!!

Answer 1

check the value of µs

75=24*9.8*0.32
75.26 close enough

now
53=24*9.8*µk
µk=0.225
