A projectile is launched from ground level at an angle θ with
respect to the horizontal and experiences only a gravitational force.
The maximum height?
The time of flight until impact?
The range (maximum horizontal distance) at impact?
The known facts:
x(0) = 0, y(0)=0;
vx(0)=vocos θ and vy(0)=vosin θ;
y(timpact) = 0.
Using these facts in the equations of kinematics, we will answer questions 1. - 3.
