Old Isaac took a little nosedive from his perch on Mrs. Cohen’s window ledge 25 feet above ground. Given that he fell as a result of a gentle tap to his noggin, how fast is Isaac traveling when he hit’s the ground? (gravity is -32ft/sec^2).

25ft=½(32ft/sec^2)t^2

t=1.25sec

-32ft/sec=(vf - 0)/1.25s

Vf=-40ft/sec
