7.
A 225-kg crate is pushed horizontally with a
force of 710 N. If the coefficient of friction
is 0.20, calculate the acceleration of the crate.
| 8.
An 18.0-kg box is released on a 37.0° incline and
accelerates down the incline at 0.270 m/s². Find the fric
tion force impeding its motion. How large is the coeffi-
cient of kinetic friction?
