Ahailstone 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. 12 meters/second2
b. 1.5 × 102 meters/second2
c. 78.6 meters/second2
d. 6.5 × 10-3 meters/second2

The magnitude of its acceleration in the water is 1.5*10² meters/second²

Explanation:

Acceleration tells us how the speed changes. Therefore, it relates the changes in speed with the time it takes to produce. So

The speed change is ending speed - starting speed. So in this case, the speed change is 0 - (43 m/s) = -43 m/s . [ You know that the hailstone travels with a speed of 43 meters / second (initial speed) and stops (final speed = zero) 0.28 seconds after hitting the water.]

And time spent changing speed is 0.28 seconds.

Considering the speed change module, that is the number regardless of the sign:

acceleration=153.57 m/s²≅1.5*10² meters/second²

The magnitude of its acceleration in the water is 1.5*10² meters/second²

the independent variable, or the one that is intentionally manipulated is the speed.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
