A 28.6 kg crate is placed at the bottom of an 23.0° incline whose surface is rough enough that the coefficient of kinetic friction is 0.371. A rope is then attached to the crate and, by pulling parallel to the incline, accelerates the stationary crate, during which the crate moves 6.30 m up the incline in 17.9 s. What is the tension (in N) supplied by the rope?
