A(n) 0.576 kg soccer ball approaches a player horizontally with a speed of 20.9 m/s. the player illegally strikes the ball with her hand and causes it to move in the opposite direction with a speed of 9.73 m/s. what is the magnitude of the impulse delivered to the ball by the player?

17.6kg.m/s in the opposite direction of the initial velocity.

Explanation:

In order to solve this we can use the Impulse-Momentum theorem:

We will assume the motion of the ball approaching the player as positive, so:

So the impulse is 17.6kg.m/s in the opposite direction of the initial velocity.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
