The following are ordinary physics problems. Place the answer in scientific notation when appropriate and simplify the units (Scientific notation is used when it takes less time to write than the ordinary number does As an example 200 is easier to write than 2.00x102, but 2.00x108 is easier to write than 200,000,000). Do your best to cancel units, and attempt to show the simplified units in the final answer. You do not need to know what any of the variables stand for, just do the math and come up with a numerical answer with correct units a.
