A student at the top of a building of height h throws ball 1 upward with a speed of vi and then throws ball 2 downward with the same initial speed, vi. How does the final speed of ball 1, v1f, compare to the final speed of ball 2, v2f, when they reach the ground?
v1f = ______ multiplied by v2f
a = delta v/delta t
vf = vi + a(delta t)
The Attempt at a Solution
I drew a picture showing the person throwing ball 1 upward and then it descending and ball two falling to the ground.
