A 4.40-kg block is placed on top of a 5.50-kg slab. If the slab is held fixed, the block can be made to slip only if a minimum force of 12.0 N is applied to it. The assembly is now placed on a horizontal, frictionless surface, as shown in the diagram.
a) What is the coefficient of static friction between the block and the slab?
b) What is the maximum horizontal force, F that can be applied to the slab so that the slab and the block will move together without relative slippage?
c) What acceleration of the system results if that force is applied? Per teacher, there is no friction between the bottom one and the 5.50Kg, but there is friction between the 4.40 kg and the 5.50Kg.

d) Suppose a horizontal force were applied to the block rather than the slab what maximun force that can be applied without producing relative slippage between the block and slab? e) What acceleration of the system results if that force is applied?
An electric power plant generates electricity @ 22 kV and 100 A. The voltage is stepped up to 240 kV before being transmitted to a city 15 km away over a copper wire that has a radius of 2 mm. Energy is lost in heating the wire during transmission. I..
