PRACTICE IT Use the worked example above to help you solve this problem. A person measures the height of a building by walking out a distance of 49.1 m from its base and shining a flashlight beam toward the top. When the beam is elevated at an angle of 40.5° with respect to the horizontal, as shown in the figure, the beam just strikes the top of the building. Find the height of the building and the distance the flashlight...

You have two people, one of whom is standing at the bottom of a building and another who is standing at the top. The person at the bottom of the building throws a ball vertically upward at 40.0 m/s at the same instant the person at the top releases an identical ball from rest. If the vertical distance between release points is 1.00 x 102 m how far from the top of the building do the two balls meet? Ignore...
