A baseball $($radius $\mathrm{.}0366m,$ mass $\mathrm{.}145kg)$ is dropped from rest from the top observation

deck of the CN Tower $(447m).$ Calculate

a$)$ the initial potential energy and

b$)$ the final kinetic energy of the baseball. Include air resistance. with

$c_2=\mathrm{.}22D^2,D$ the diameter of the object$).$ Hint: review the tutorial #$2$ solution.

c$)$ What is the work done by air resistance over the ball's entire trajectory?
