Question: An airplane is dropping bales of hay to cattle stranded in a blizzard on the Great Plains. The pilot releases the bales at 140m above the level ground when the plane is flying at 60.0m/s 50.0 degree above the horizontal.
Part A: How far in front of the cattle should the pilot release the hay so that the bales will land at the point where the cattle are stranded?
