Astone is dropped into water from a bridge 52 m above the water's
surface. what can be determined about the stone as it reaches the
water?

Its final velocity and how much time it takes to reach the water

Explanation:

The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:

where

v is the final velocity

u = 0 is the initial velocity

is the acceleration of gravity

s = 52 m is the distance covered during the fall

Solving for v,

We can also find how much time it takes to reach the water, using the equation

where

v = 31.9 m/s is the final velocity

u = 0 is the initial velocity

t is the time

And solving for t,
