Asked by Jacqueline
A stunt man drops from the top of a 50 foot elevator shaft. His height above ground is determined by the equation h=-16(t)(t)+50. At the moment the stunt man begins to drop, an elevator goes up so that its height above ground is determined by the equation h=34t. After how many seconds will the stunt man land on top of the elevator.
I solved using the quadratic equation and obtained an answer of 3.125 seconds or t=-1...is this correct? Thanks!
