A Box Sliding Down an Incline with Friction: Total Force

APPHMC-HP0OXN

A box slides down a $45^o$ ramp, where the coefficient of friction between the box and the incline is given by $\mu_k = 0.8$. The box has mass $1.6 kg$.

As it slides, how much total force does the box exert on the incline?

A

$8.9 N$

B

$11.1 N$

C

$12.7 N$

D

$14.2 N$

E

$15.7 N$
