A crate is pushed horizontally by a horizontal force 1087.26 N . Sliding friction resists the

motion, and the kinetic coefficient of friction
is 0.22 .
The acceleration of gravity is 9.8 m/s
2
.
Calculate the acceleration of the crate.
Answer in units of m/s
2
.

you need the mass of the crate to calculate its weight and the friction

and just write m/s^2 instead of that annoying newline.

In any case, recall that F = ma
