Calculating the Force Needed for Constant Velocity of a 15 kg Crate on a Floor

[Medgirl314]

Homework Statement

A 15 kg crate rests on the floor. The coefficient of kinetic friction between the crate and the floor is 0.28. How much horizontal force is needed to slide the crate across the floor at a constant speed?

Homework Equations

F_net=ma

The Attempt at a Solution

F=MN
Mmg=.28*15 kg*9.8

41.16 N
For a final rounded answer of 41.2 N.

This answer seems plausible to me, would someone please confirm?

Thanks!
