you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

good looking response

no. dot product   =0 when vecs at right angles

c) up is the direction the magnetic force is acting on the charge.
