For the first part, use conservation of energy, and let Vo be the initial veloicty
(Vo^2)/2 = gH
Solve for maximum height H
H = 240 m
Time to reach maximum height
= H/V(average) = 240/34.3 = 7.43 s
An object is fired vertically upward with an initial speed of 68.6 meters/second.
After t seconds, the height is shown by y= -4.9t^2+68.6t meters. Given that this object has an initial speed of 68.6 m/s, what is the maximum height it will reach?
How long did it take the rocket to reach the maximum height?
