Asmall ball of mass m is
travelingwith an initial velocity v in the positive
xdirection. it collides with a larger ball of mass m that
is initially at rest. after the collision, the smaller ball isat
rest. what is the final velocity, v, of the
largerball?
a.) v=v
b.) v= -v
c.) v= 0
d.) v= (m/m)v
e.) v=(m/m)v
answer and explanation would be great. if you dont know
not answer.

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
