I need the algorithm to animate the arrow based on 2 parameters, angle while shooting and power while drawing the bow.
Ive tried to use y=asinx but it works only when shooting in up direction. Doesnt work well while shooting with straight or down direction. Thanks.

    The flight of your projectile is described by 

    x(t) = v * cos(theta) * t
y(t) = v * sin(theta) * t - 1/2 * g * t^2

    where t is time, v the initial velocity (power), theta the angle, g the acceleration due to gravity (e.g. 9.8 m/s^2), x the horizontal coordinate and y the height.
