A dockworker applies a constant horizontal force of 80.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves 11.0 m in 5.00 s.
1) What is the mass of the block of ice?
2) If the worker stops pushing at the end of 5.00 s, how far does the block move in the next 5.00 s?

For laminar flow over a flat plate, the local heat transfer coefficient $h_{x}$ is known to vary as $x^{- \frac{1}{2}}$ , where x is the distance
from the leading edge (x=0) of the plate. What is the ratio of the average coefficient between the leading edge and some
location x on the plate to the local coefficient at x?

Getting your pre Algebra solved becomes much easier when you have all the answers to your questions by taking a closer look at the various examples dealing with Pre-Algebra subjects. We have intentionally collected the list of pre-algebra equations and various solving equations with decimals problems to help you see various examples that explain how certain solutions are found. Still, if something sounds unclear or you are concerned about some solution that has been provided, approach pre-algebra with reverse engineering approach (going backwards).
