Agirl throws a stone from a bridge. consider the following ways she might throw the stone. the speed of the stone as it leaves her hand is the same in each case, and air resistance is negligible. case a: thrown straight up. case b: thrown straight down. case c: thrown out at an angle of 45 above horizontal. case d: thrown straight out horizontally. in which case will the speed of the stone be greatest when it hits the water below?

The speed of the stone hitting the water below will be the same for every case.

Acceleration is rate of change of velocity.

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

Given:

height of the stone = h

initial speed of the stone = u

Unknown:

final speed of the stone = v = ?

Solution:

From information above , we could conclude that the speed of the stone hitting the water below will be the same for every case.
