Suppose that a 5footlong chandelier falls from a 35foot 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+(3556) (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 ????
