Question

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. (a) How much time does Greezy have until it's time for pumpkin pie (IOW, until it smashes into Greezy)? (b) Assuming Greezy does not have his wits about him, at what location above the ground will the pumpkin intersect with him?

Explanation / Answer

Distance to be covered=1200m

Relative velocity=145+25=170m/s

time=1200/170=7.06s

Distance above ground=7.06*145=1023.5n
