Suppose that a 5-foot-long chandelier falls from a 35-foot ceiling and that you are 6 feet tall and standing directly under the chandelier

(a) How long do you have to get out of the way when it drops?
=-16(t^2)+Vt+h
=-16(t^2)+0+(35-5-6) (for the bottom of the chandelier and your head)
=-16(t^2)+24
16(t^2) = 24
t^2 = 1.5
t= 1.2247

(b)If you do not duck or get out of the way, how fast will the chandelier be traveling when it hits your head?
=-32(t)+Vot
=-32(1.2247) + 0
=-39.19 ft/sec ????
