Question

Question:
A crate with a mass of 100 kilograms is subjected to two forces: an 800 newton force directed 30 degrees below the horizontal, pushing to the right and downward, and a 1000 newton rope force directed at an angle whose slope components are 3 vertical and 4 horizontal — that is, at the arctangent of 3 over 4 above the horizontal — pulling to the right and upward. The crate starts from rest on a horizontal surface with a coefficient of kinetic friction mu sub k equal to 0.2. Determine the distance s the crate must slide to attain a speed of 6 meters per second.

Problem 14-3: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the work-energy theorem to find the distance a crate must travel to reach a target speed when subjected to two angled forces and kinetic friction. Students resolve forces into components, compute the normal and friction forces, then
