Question

Question:
A 100-kilogram crate is subjected to two forces: a 500-newton force directed at 45 degrees above the horizontal, pulling upward and to the left, and a 400-newton force directed at 30 degrees below the horizontal, pushing inward from the right. The crate is originally at rest on a horizontal surface. Determine the distance s it must slide in order to attain a speed of v equals 8 meters per second. The coefficient of kinetic friction between the crate and the surface is mu sub k equals 0.2. Use the work-energy principle.

Problem 14-4: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the work-energy principle to a crate acted on by two applied forces at different angles and kinetic friction on a horizontal surface. Students resolve each force into components, compute the normal force, determine friction, and use the work-energy theorem to find the dist
