Question

Question:
A 150-gram ball is kicked such that it leaves the ground at an angle of 60 degrees and strikes the ground at the same elevation a distance of 12 meters away. Determine the impulse of the foot on the ball. Neglect the impulse caused by the ball's weight while it is being kicked.

Problem 15-1: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the principle of impulse and momentum to a projectile problem. Students determine the launch speed of a ball from its known range and launch angle, then use the impulse-momentum theorem to find the magnitude and direction of the impulsive force. The weight impulse is neglected during the very short impact interval.

In this lesson, you will learn to:
• Apply the principle of linear impulse and momentum to relate an impulsive force to the change in momentum of an object
• Use projectile kinematics to determine the
