2.70 Egg Drop.You are on the roof of the physics build ing, 46.0 m above the ground (Fig. P2.70). Your physics pro fessor, 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.

2.70 Egg Drop.You are on the roof of the physics build ing, 46.0 m above the ground (Fig. P2.70).

Jeffrey Jordon · Accepted Answer

Time taken by flower to free fall =t and distance rquired to fall =44.2 m  S=μt+12​gt2  ⇒44.2=0t+21​×98×t2  ⇒t2=3 s  ∴ Professor should be at distance of 3×1.2=3.6 m
