Q1. A plane leaves the airport in Galisto and flies 145 at 68 east of north and then changes direction to fly 225 at 48 south of east, after which it makes an immediate emergency landing in a pasture.
When the airport sends out a rescue crew, how far should this crew fly to go straight to this plane?
Q2. A vertical container with base area measuring 16 cm by 18 cm is being filled with identical pieces of candy, each with a volume of 50 mm3 and a mass of 0.020g. Suppose that the volume of the empty spaces between candies is negligible. If the height of the candies in the container increases at the rate of 0.230cm/s, at what rate (kilograms per minute) does the mass of the candies in container increase?
