Homework Statement
You are on the roof of a physics building, which is 46.0 m above the ground. Your physics professor, who is 1.80 m tall, is walking alongside the building at a constant rate of 1.20 m/s. If you wish to drop an egg on your professor's head, how far from the building should the professor be when you release the egg?
Homework Equations
The Attempt at a Solution
I took 46.0 and subtracted 1.80 for the height of the professor. That gave me 44.2 m. I then divided that by 9.80 m/s^2 for acceleration due to gravity. That gave me 4.51 s. I then divided that by 1.20 m/s for the velocity of the professor. This gave me an answer of 3.76 m. I typed this in and the masteringphysics said not quite, that I may have a slight error in calculuation or used the wrong number of significant figures. I recalculated several times and kept getting 3.76. Any ideas?
