Cargo is tied with rope on the roof of a 4.5-foot-tall car. The car travels down a road at 40 mi/h and hits a concrete barrier and the rope snaps, allowing the cargo to propel forward. Find the time it takes for the cargo to hit the ground and the horizontal distance the cargo travels. Let y represent height in feet, let x represent horizontal distance in feet, and let t represent time in seconds.
Equation 1: y = –16.1t² + 4.5
Equation 2: y = –0.0047x² + 4.5
