After being struck by a bowling ball, a 1.6 kg bowling pin sliding to the right at 4.7 m/s
collides head-on with another 1.6 kg bowlilas
pin initially at rest.
Find the final velocity of the second pin in
the following situations:
a) The first pin moves to the right after the
collision at 0.5 m/s.
Answer in units of m/s.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
