Question

5 a soccer ball is traveling at a rate of 10 m/s and then is kicked again at a speed of 15 m/s. the diagram below shows the direction the ball is moving before and after the second kick. which of the following statements correctly identifies what is happening to the speed and velocity of the soccer ball? a speed changing, velocity changing b speed constant, velocity constant c speed changing, velocity constant d speed constant, velocity changing

Explanation:

Speed is a scalar quantity (only magnitude), and velocity is a vector quantity (magnitude and direction). The ball's speed changes from \(10\ m/s\) to \(15\ m/s\). Also, the direction of the ball's motion changes (as shown by the arrows in the diagram). Since both speed (magnitude) and direction (for velocity) change.

Answer:

A. Speed changing, velocity changing
