Question

please help In a video game, a ball moving at 0.6 meter/second collides with a wall. After the collision, the velocity of the ball changed to -0.4 meter/second. The collision takes 0.2 seconds to occur. What’s the acceleration of the ball during the collision? Use . a= v-u/t

    Answer:

    the acceleration during the collision is: – 5  \frac{m}{s^2}

    Explanation:

    Using the formula:

    a=\frac{\Delta\,v}{\Delta\,t}

    we get:

    a=\frac{-0.4-0.6}{0.2} \,\frac{m}{s^2} =\frac{-1}{0.2} \,\frac{m}{s^2} =-5\,\,\frac{m}{s^2}
