Question

Anita Knapp needs to get hay to cows in a frozen field using an airplane flying 80.0 m/s, at a height of 300,m. If at the last minute, how far from the cow would she have to release the hay in order to hit the cow? *

Answer 1

Step-by-step explanation:

If we ignore wind resistance, the time needed for the hay to drop from vertical rest is

t = √(2h/g) = √(2(300)/9.81) = 7.82 s

d = vt = 80.0(7.82) = 626 m before passing over the cow.
