A friend is holding a potato gun at a 40 degree angle from the very bottom. It sends out a potato which travels a horizontal distance of 850m. a. How long does it take the potato to hit the ground? b. Your friend has unfortunately not so much as held the potato gun as wedged it in the ground, supporting it vertically but not horizontally. As a result, the bottom end that they hold doesn't move, but the top of the gun moves backward in a circle due to the torque of the recoil. If the potato gun is 2 meters long, and your friend's face is also about 2 meters above the ground, so that it collides with the potato gun once the gun has become vertical, then how quickly is the gun moving when it hits your friend's face?
