Question

You are on the roof of the physics building, 46.0 m above the ground. Your 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 toss an egg on your professor's head, where should the professor be when you throw the egg? Initial velocity is shown in the figure 2. 3 m/s 46.0 m u = 1、20 m/s 1.80 m

The egg should fall on professors head

time taken for egg to reach head and professor to reach that egg should be same

t = sqrt(2h/g) = x/1.2

h = 46 - 1.8 = 44.2 m

g = 9.8 m/s^2

Therefore, x = 1.2 * sqrt(2*44.2/9.8) = 3.604 m

professor should be at a distance of 3.604 m
