If the stone enters the water at 41.6 ms-1, and takes 0.6s to travel the 3 meters to the bottom of the pond, what is its average acceleration in the pond water?
The distance travelled under a constant acceleration is given as follows:
where is the depth of the pond, is time of movement, is the initial velocity, and is the required average acceleration. Expressing , find:
Answer. 122 m/s^2.
