Chapter 3, Problem 3/3

(choose chapter or problem)

At a certain instant, the 80 -lb crate has a velocity of \(30 \mathrm{ft} / \mathrm{sec}\) up the \(20^{\circ}\) incline. Calculate the time t required for the crate to come to rest and the corresponding distance d traveled. Also, determine the distance \(d^{\prime}\) traveled when the crate speed has been reduced to \(15 \mathrm{ft} / \mathrm{sec}\).
