Question

A model rocket is launched straight into the air from platform 3 feet above the ground with an intial velocity of 192 feet per second

Answer 1

Explanation:

the function -16t^2 + 64t + 192 give the height S, in ft, of a model water rocket launched with a velocity of 64 ft/second from a hill that is 192 ft high. a) determine how long it will take the rocket to reach the ground, b) find the interval on which the height of the rocket is greater than 240 ft.
