Question

Question:
A hockey puck is traveling to the left with a velocity of v1 equals 10 meters per second when it is struck by a hockey stick and given a velocity of v2 equals 20 meters per second directed at 40 degrees above the horizontal, to the upper right. Determine the magnitude of the net impulse exerted by the hockey stick on the puck. The puck has a mass of 0.2 kilograms.

Problem 15-5: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the impulse-momentum theorem to a two-dimensional collision between a hockey stick and puck. Students decompose initial and final velocity vectors into components, compute the change in momentum, and find the magnitude and direction of the net impulse vector.

In this lesson, you will learn to:
• Apply the vector form of the impulse-momentum principle: $\vec{J} = m\vec{v}_2 - m\vec{v}_1$
• Decompose velocity vectors into x- and
