Question

A hailstone traveling with a velocity of 43 meters per second comes to a virtual stop at 0.28 seconds after hitting water.what is the magnitude of it acceleration in water

Answer 1

Magnitude of acceleration = (change in speed) / (time for the change)

Change in speed = (final speed) minus (initial speed)

= ( zero ) minus (43 m/s) = - 43 m/s .

Magnitude of acceleration = ( - 43 m/s ) / (0.28 sec) = - 153.6 m/s²

(about - 15.7 G's)

Answer 2

For Plato users the best answer will be 1.5 x 10^2 meters/second^2
