a pair of glasses is dropped from the top of a 36.0 m high stadium. a pen is dropped from the same position 2.21 seconds later. how high above the ground is the pend when the glasses hit the ground? (disregard air resistence. a=-g=-9.81 meters per second squared)

Question

a pair of glasses is dropped from the top of a 36.0 m high stadium. a pen is dropped from the same position 2.21 seconds later. how high above the ground is the pend when the glasses  hit the ground? (disregard air resistence. a=-g=-9.81 meters per second squared)

drwls · Accepted Answer

Calculate how long it takes the glasses to hit the gound.

36.0 = (g/2) t^2

t = 2.71 s

The pen will have been falling 2.71 - 2.21 = 0.50 seconds when the glasses hit the ground. Use that information to compute where pen is at that time.

You do that part.
