Newton law Applications. Any suggestion

[tubspring]

A mass M at To =0 s has a speed of lVol in the positive X direction. The floor has a coefficient of static friction of Us and a coefficient of kinetic friction of Uk. How far will the mass M travel?

mass = M
@ To = 0s
speed = Vo
coefficient of static friction = Us
coefficient of Kinetic friction = Uk

w=-mg
a=?

I don't really know how to start to my problem.
any hint?

Thanks!

hi tubspring! welcome to pf!

(have a mu: µ and try using the X₂ icon just above the Reply box )

use the work-energy theorem ​

(if you don't know that, then use good ol' Newton's second law to find the acceleration, then use the standard constant acceleration equations)
