You are on the roof of the phusics building, `46,0 m` above the ground (Fig.4.40). Your physics professor, who is `1.80 m` tall, is walking alongside the bulding at a constant speed of `1.10 m s^(-1)`. If you wish to drop a flower on your professor`s head, where should the professor be when you release the flower? Assume that the flower is in free fall.
.

Text Solution

Verified by Experts

The time needed for the egg to fall is
`tsqrt((2Deltah)/(9)) =sqrt((2(46.0m-1.89 m))/((9.80 ms^(-2))))=3.00 s`
and so the professor should be at a distance
`v_(y)t=(1.20 ms^(-1))(3.00 s)=3.60 m`.
