A ball rolling across a field with an acceleration of -0.5 m/s² rolls 12.5 m and then comes to a stop after 8 seconds. What was the ball's initial speed?

Question

Quizplus · Accepted Answer

The initial speed can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Since the ball comes to a stop, the final velocity is 0. Therefore, 0 = initial velocity - 0.5 * 8, which gives an initial velocity of 4 m/s.
