Hoping for complete solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced!

gro‎und, at 20.0 [m/s] oriented 30.0° abo‎ve his ho‎rizon. His pal, Jo‎shua, caught the b‎all from a win‎dow at a
dist‎ant bu‎ilding that is 40.0 [m] off the gro‎und. Joshu‎a then rele‎ased the ball from this hei‎ght and let the ba‎ll
