A quick question i have some of you canhelp me with, i have sort of worked it out just need to see what everyone else got?
The frictional force F newtons and load L are connected by the law F = aL = b. When F = 6.0 N, L = 7.5N and when F =2.7N, L = 2.0N
What do you come up with?
thanks in advance for any help (Yes)
Sorry seems it hasnt posted all the question, i need to calculate the value of A and B.
The way you've stated your formula 'F = b'. You already know F in each case. So, you also know b.

Dont know how right this is but heres what i done:
if F=6 and L=7.5
a = 6/7.5 = 0.8
If thats incorrent can any one help me to get the value of A and B?
F = aL = b
do you mean F = aL + b
then you have 2 simultaneous equation.
