Question

Question:
A 20-kilogram crate is subjected to a force having a constant direction and a magnitude F equal to 100 newtons, applied at 30 degrees above the horizontal. When s equals 15 meters, the crate is moving to the right with a speed of 8 meters per second. Determine its speed when s equals 25 meters. The coefficient of kinetic friction between the crate and the ground is mu-sub-k equal to 0.25.

Problem 14-1: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the Principle of Work and Energy to find the final speed of a crate acted on by an angled constant force and kinetic friction over a given displacement. Students learn to compute the normal force accounting for the vertical component of the applied force, calculate work done by each force, and solve for the unknown speed using the work–energy equation.

In this lesson, you will learn to:
• Apply the Wor
