A beach ball, moving with a speed of +1.28 m/s rolls off a pier and hits the water a horizontal distance of 0.74 m from the end of the pier. How high (magnitude only) above the water is the pie?

The height of the pier above the water is not given, so we cannot calculate the exact height of the beach ball above the water. However, we can calculate how long it took for the beach ball to reach the water. Using the equation v = d/t, we can solve for t by rearranging the equation: t = d/v. We can then calculate t as 0.58 seconds. Dividing the height of the pier by 0.58 seconds will give us the approximate height of the beach ball above the water.
