A coin is tossed straight up with an initial speed of 20 m/s from a surface. When the coin returned it falls into a 10 m deep PVC pipe below the surface. a. What is the coins velocity as it reaches the bottom of the PVC pipe? b. How long is the coin in the air, from the moment it is released until it hits the bottom of the hole?

Joe was assigned to an expedition to the Arctic by the government to find the wrecks of a ship that has been lost for 100 years. During his first day, he decided to explore the area riding a snow mobile, He traveled 185 miles south from the base camp and then turned and drove 70 miles west. After finding nothing, Joe decided to return to the camp.a. In what direction must he drive to go back to camp?b. Joe noticed that his snow mobile's gas level is only a quarter full. He estimates that he can still travel for 150 miles with the remaining gas. Will his snow mobile's gas be enough to reach camp?c. If the gas was not enough, how much distance will Joe have to walk to reach the base camp?
The bottom of a car hits a sharp rock, which punctures a small hole on the bottom of its gas tank. If the height of the gasoline in the tank is 30 cm and the surface of the gas in the tank is exposed to atmospheric pressure (since the lid is not tightly sealed), determine the initial velocity of the gasoline pouring out of the hole. Answer in m/s.
