Problem 13-4: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

Question:
A 50-kilogram crate starts from rest and achieves a velocity of 4 meters per second when it travels a distance of 5 meters to the right. Determine the magnitude of force P acting on the crate. The force P is applied at an angle of 30 degrees above the horizontal. The coefficient of kinetic friction between the crate and the ground is mu-k equals 0.3.

Problem 13-4: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies Newton's second law to a crate accelerating on a rough horizontal surface under an angled applied force. Students use kinematics to find acceleration, then set up and solve equations of motion in both the vertical and horizontal directions to determine the unknown force magnitude.

In this lesson, you will learn to:
• Use a kinematic equation to determine constant acceleration from initial velocity, final velocity, and distance.
• Construct
