Problem: You are standing on the top of a 13 m tall building and throw a bouncy ball whose mass is 0.1 kg at a taller building that is 8 m away. You throw the ball at shoulder height about 1.4 m above the top of the roof at an angle of 25 degrees below the horizontal at a speed of 18.5 m/s.
Part A: What is the speed of the bouncy ball just before it hits the ground?
I need help to find the speed of the bouncy ball just before it hits the ground.
