A $500$ g squirrel with a surface area of $925$ cm$\mathrm{²}$ falls from a $4\mathrm{.}4-$m tree to the ground.

 a$)$ Estimate its terminal velocity. $($Use the drag coefficient for a horizontal skydiver. Assume that the squirrel can be approximated as a rectangular prism with cross$-$sectional area of width $11\mathrm{.}5$ cm and length $23$ cm$.$ Note, the squirrel may not reach terminal velocity by the time it hits the ground. Give the squirrel's terminal velocity, not it's velocity as it hits the ground.$)$ 

b$)$ What will be the velocity of a $50\mathrm{.}0$ kg person hitting the ground, assuming no drag contribution in such a short distance?
