You have a machine that launches a brick at a speed
,
above the horizontal. You can use this device to measure the height of a building.
- a.
- Given
,
and the distance d that the brick lands from the building, find an equation for the height h of the building in terms of
,
, and d.
- b.
- You use this machine set at initial speed 10. meters per second and
= 30 degrees. You find that the brick lands 18m away from the base of a building. How high is it?
