b. transform to new frame where particle is at rest. and compute the force on the particle in the boosted frame.

c.the charges if the proton and electron and gravity

an energy transformation flow diagram is shown

where is it ?

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

there are no contact forces mentioned on the list of choices that you've provided.
