What is the maximum altitude reached?
|
find the distance traveled when the power is on using kinematics, then use trigonometry to find the altitude

Find the time of flight from launch to impact.
|
So, the time of flight from launch to impact = 23 seconds + t
When the engines shut off, the velocity in y-direction = 0. Find t.

What is the horizontal distance between the launch pad and the impact point?
|
total horizontal distance = horizontal distance when power is on + horizontal distance of parabolic motion
