E = a + kL
a+20k = 1.4
a+30k = 2.0
Now just solve for a and k, and then go for L=50
different questions pls! Very urgent!
1) the force E needed to make a machine pull,a load is partly constant and partly varies as the load to be pulled itself.when the load is 20g,the force needed is 1.4n,where as the force needed for 30g load is 2N.
Find the:
A)law connecting the load and force?
B)force for the load of 50g?
