Problem 3 You're at the top of a mountain, and the mountain 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. (a) How much time does the pebble spend in free-fall before hitting the sloping ground? (Round to the nearest integer number of seconds.) (b) How far down the slope does the rock land? (c) What is the speed of the rock when it lands? Vo = 10 m/s
