Homework Statement
A rocket launched at 70 degrees to the horizontal has a constant net acceleration of 8m/s^2 along this direction for 6.5s and then is in free-fall.
Find: (a) the maximum height; (b) the horizontal range.
Homework Equations
Kinematics equations (along x and y)
The Attempt at a Solution
I know that at the initial position, along x: position=0, velocity=V0cos70 and acceleration=8cos70. along y: position=0, velocity=V0[SUB/]sin70 and acceleration=8sin70.
