A car is traveling at 68 km/h. Cargo is strapped to the roof at a height of 1.6 m. The car hits a concrete barrier, and the cargo is horizontally ejected off the roof. Use these two equations to determine how long it takes for the cargo to hit the ground and how far it travels in the horizontal direction. y = –4.9t² + 1.6 and y = – 0.0136x² + 1.6 where y represents the height in meters, x represents the horizontal distance in meters, and t represents the time in seconds.
