Part 1

A model rocket is launched into the air from a platform 10 feet above the ground. The initial velocity of the rocket is 50 feet per second. The height, h, of the rocket’s trajectory can be modeled by the function h(t)=–16t2+50t+10, where t is the time in seconds since the rocket was launched.

Approximately how many seconds does it take for the rocket to reach its maximum height? Round your answer to the nearest tenth of a second.
