If the co-efficient of static friction for a 5 kg rubber block is 0.3 how much more force is required to lift the block than to start it sliding?
I worked out force to get it sliding is 14.7 N (5*9.8*.3) but not sure about the upward force to lift it.

Thanks. This is what I thought but again the answer in my book was incorrect. So frustrating.
