A person stands next to a three-story building with windows that are hw in height. The windows are separated by gaps of height, hg. A person standing on the sidwalk outside of the building throws a ball straight up with speed v1 from the bottom of the first-floor window. After rising above the building, the ball falls and is caught by a friend at the top of the highest window. Suppose the ball is thrown at time, t1, and caught at time, t2. Required:
Identify the variables that have been discussed in the paragraph above with the standard variables that appear in the kinematics equations.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

that would be because of both gravity and friction. so     c

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

i think it would be 5
