Asked by Edge

You are on the roof of the physics building, 46 m above the ground. Your physics professor, who is 1.80 m tall, is walking alongside the building at a constant speed of 1.20 m/s. If you wish to drop an egg on your professor’s head, where should the professor be when you release the egg? Assume that the egg is in free fall.

Thanks in advance!

How long to fall 46-1.8 = 44.2 meters ?

44.2 = (1/2) g t^2

t = sqrt (88.4/9.81)

t = 3 seconds

d = u t = 1.20 * 3 = 3.6 meters

In last s= ut-1/2at^2 is not taken and only s=ut is taken?

ou are standing on the sci.com. building 46.0 m high above the ground. Your classmate, 1.8 m tall, is walking alongside the building at a constant speed of 1.20 m/s. If you wish to drop an egg onto his head,
a) where should he be when you release the egg? Assume that the egg is in free fall.
Time taken by flower to free fall =t and distance rquired to fall =44.2m
b) what will be the velocity of the egg when it hits his head?
