A mango rolls off the roof of a house from a height of 31 feet at an angle of 30 degrees with respect to the horizontal. It leaves the roof at a speed of 4.2 ft/s and falls to the ground. Determine the time it takes for the mango to reach the ground in seconds. DO NOT enter units.
![A projectile is launched of the top of a tower with an initial velocity of 70 [m/s] at an angle of 37 degrees with respect to the horizontal axis. The tower is 30 [m], meaning the projectile is launched at a height of 30 [m] above the ground. To simplify the math in the problem use: g = 10 m/s2 sin(37degrees) = 0.6 cos(37degrees) = 0.8 See figure below: What is the maximum height achieved by the projectile as measured from the ground? 118.2 [m] 188.2 [m] 144.1 [m] 88.2 [m] 44.1 [m]](https://www.doubtrix.com/uploads/editor/6994826109BUGcvpaZzG.jpg)
