[Terjawab] A projectile is launched off the roof of a 200-meter-tall building close to its edge, where the initial velocity's horizontal component is [tex]$10 m / s$[/tex] and its vertical component is [tex]$15 m / s$[/tex]. If the projectile lands on the ground below, how far from the building's side (in meters) does the projectile land? Round your answer to the nearest hundredth (0.01). Hint: Find the time it spends in mid-air using the quadratic equation, then use that time to find the distance. If [tex]$A t^2+B t+ C =0$[/tex], then [tex]$t=\frac{-B+\sqrt{B^2-4 A C}}{2 A}$[/tex] It should give you two values for time; make sure to pick the right one!
