Compute each part of given problem:
Problem: Next to music, Greezy's favorite hobby is skydiving. He jumps out of a plane and, after opening his parachute, reaches a constant terminal velocity of 25 m/s. When he is 1200 m above the ground, Skid, standing directly below Greezy, launches a pumpkin straight up into the air at Greezy. The pumpkin has an initial velocity of 145 m/s.
Part A: How much time does Greezy have until it's time for pumpkin pie (IOW, until it smashes into Greezy)?
Part B: Assuming Greezy does not have his wits about him, at what location above the ground will the pumpkin intersect with him?
I've been having quite a bit of trouble understanding this problem, Thank you so much for your help. Thanks.
