Textbook Question
Chapter 3, Problem 13CQ
There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target. A pilot flying low and slow drops a weight; it takes 2.0 s to hit the ground, during which it travels a horizontal distance of 100 m. Now the pilot does a run at the same height but twice the speed. How much time does it take the weight to hit the ground? How far does it travel before it lands?

You’re at the top of a mountain, which slopes down at a 45 degree angle below the horizontal. You throw a pebble horizontally from the top of the slope, with an initial speed of 10 m/s. How much time does the pebble spend in free-fall before hitting the sloping ground? (Round to the nearest integer number of seconds.)
