A group of hikers hears an echo 4.20 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 341 m/s.) m
you are trying to launch a care package to someone who is stranded on the side of a mountain until they can be rescued. Your care package launcher is capable of shooting the package at 89 m/s at 70° above the horizontal. How far away should we place the launcher if the stranded person is 270 m above your location?
A plane drops a package of food to stranded caribou on an ice flow in the Arctic circle. The plane flies 207.11 m above the ice at a speed of 144.48 m/s. How far short of the target should it drop the package?
(Figure 1)A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 462 km/hour at an altitude of 575 m. The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the...
