A projectile is launched from ground level at an angle θ with respect to the horizontal and experiences only a gravitational force.

What is:

1. The maximum height?
2. The time of flight until impact?
3. The range (maximum horizontal distance) at impact?

The known facts:

• x(0) = 0, y(0)=0;
• v_x(0)=v_ocos θ and v_y(0)=v_osin θ;
• y(t_impact) = 0.

Using these facts in the equations of kinematics, we will answer questions 1. - 3.
