We can use the formula $h=\frac{v_i^2}{2g}+h_i$ where $h$ is the final height, $v_i$ is the initial velocity, $g$ is the acceleration due to gravity, and $h_i$ is the initial height. Substituting the given values, we get $h=\frac{(11)^2}{2(11)}+11=21.5$ ft. Therefore, the ball will go to a height of 21.5 ft. Choice (E) is the closest answer.

A Ball Is Thrown Vertically Upwards from a Height of
