-less than 1.5
-Between 3.0 and 4.4
-More than 6.0
-Between 1.5 and 2.9
-Between 4.5 and 6.0
Homework Equations
Fsmall= (Asmall/Alarge)*Flarge
The Attempt at a Solution
25*9.8 = (Asmall/Alarge)*(1500*9.8)
Asmall/Alarge =1/60
I know this is definitely not the right ratio, and I know I'm not including something probably in the area portion -I'm just not sure what that is
