Description: A 0.70 kg ball moving horizontally at 5.0 m / s strikes a vertical wall and rebounds with speed 2.0 m / s . What is the magnitude of the change in its linear momentum?

step 1 Our question says that we have a 0 .70 kilogram ball, which I label as M here for that mass of t

Step 1

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction. In this case, the direction of the momentum changes when the ball hits the wall and rebounds in the opposite direction. Show more…

Key Concepts

Linear Momentum

Linear momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction, and is a fundamental concept in mechanics for describing the motion of an object.

Change in Linear Momentum

The change in linear momentum, often referred to as impulse, is the difference between the final and initial momentum of an object. This quantity takes into account changes in both speed and direction, and its magnitude reflects the overall impact of an interaction, such as a collision with a wall.
