A hailstone traveling with a velocity of 43 meters/second comes to a virtual stop 0.28 seconds after hitting water. What is the magnitude of its acceleration in the water
a = change in velocity/time = (0 - 43)/.28
= - 154 m/s^2
To determine the magnitude of the hailstone's acceleration in the water, we can use the formula:
acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is 43 meters/second, and the final velocity is 0 meters/second (since the hailstone comes to a stop). The time is given as 0.28 seconds.
Plugging in these values into the formula:
acceleration = (0 - 43) / 0.28
Simplifying the expression:
acceleration = -43 / 0.28
Evaluating the division:
acceleration ≈ -153.57 meters/second^2
Therefore, the magnitude of the hailstone's acceleration in the water is approximately 153.57 meters/second^2.
