Angle of a projectile which maximizes the range? Cannot solve the equation?
where V_a is the velocity of the arrow, which is shot off of the car
V_c is the velocity of the car, which is moving in the opposite direction of the arrow
So, to find the angle I need the derivative and set it equal to 0
2V_a/g * [2V_a cos^2(theta) - V_c cos(theta) - V_a] = 0
How do I Solve it??
