Ball A is released from rest at height h1 at the same time that a

second ball B is thrown upward from a distance h2 above the

ground. If the balls pass one another at a height h3 determine the

speed at which ball B was thrown upward.

Given:

h1 = 40 ft

h2 = 5 ft

h3 = 20 ft

g =32.2 ft/sc2

2. Relevant equations

the equation to be used are the three equations of motion, as the acceleration is constant.

3. The attempt at a solution

I couldnt attempt the solution becuase I am stuck a every equation as therer are many unknowns for ball B. WHat I can not find out yet is the relation between ball A and Ball B when they pass each other. There has to be property common in both at that time so that I can solve for B then. But again, after a lot of thinking I dont get how to do it still. Couldn't make any logic. The distance traveled is already given. Time taken and velocity will not be the same. What then?
