Homework Statement
A rocket launched vertically takes 6.13 seconds in total. How much time does it take the rocket to reach its maximum height. What is the velocity of the rocket in meters per second at maximum height? What is the initial velocity of the rocket. Give your answer in meters per second.
Homework Equations
final velocity = initial velocity + (acceleration x time)
distance = 1/2 x (initial velocity + final velocity) x time
distance = initial velocity x time + 1/2 acceleration x time^2
final velocity^2 = initial velocity^2 + 2 x acceleration x distance
The Attempt at a Solution
I feel as though there is not enough information. I am not sure, but is the time it takes to reach the maximum height just half of the total time? Which would be 3.07 (rounded) seconds. So then I can use the kinematic equations to try to solve for the rest. Distance = initial velocity x time + 1/2(acceleration) x time^2 so d=0+ (9.8 x 3.07^2). So distance = 92.4 meters?
