(L2 points) A ball is thrown vertically upward with an initial velocity of 64 ft/sec from the the top of a building which is 512 fwt high (neglect air resistance and use the acceleration due to gravity to be - 82 ft/sec2 ;. find a) an equation for the height ofthe ball as a function ofthe time, b) the ma:<imum height of the ball, and c) the velocity with which the ball hits tlre ground. 2. (15 points) Find the following limits: + a) hr4 #= b) liry @ - [)(tann) c) tim ("or r)a s--ae cos fr-L 'r-1aS-' z t \ --'- -, -/ iJti* \--- -,/ 3.
