A car drove off a cliff. The cliff was 8 ft high and the car landed 45 ft away from the edge of the cliff. What was the speed when the car left the cliff?

physics 
bobpursley,
How much time does it take to fall 8 feet?
h=1/2 g t^2
8=1/2 32 t^2
t^2=1/2
t= .707 sec
distance= Vi*.707=45
vi= 45*sqrt2 ft/sec
