Question

Question:
A 10-pound block has a speed of 4 feet per second when a horizontal force F equals 8t-squared pounds is applied. Determine the velocity of the block when it has moved s equals 30 feet. The coefficient of kinetic friction is mu-sub-k equals 0.2.

Impulse-Momentum with a Time-Dependent Force and Kinetic Friction

This lesson solves for the velocity of a block subjected to a time-varying horizontal force and kinetic friction after traveling a specified displacement. Because the applied force is a function of time, the impulse-momentum method is combined with kinematic integration to relate time and position, and the result is verified with the work-energy theorem.

In this lesson, you will learn to:
• Apply Newton's second law to write the equation of motion for a block with a time-dependent applied force and kinetic friction.
• Integrate the equation of motion to obtain velocity
