A Physics question regarding circuits and electricity.

Ball b is hanging from an inextensible cord. an identical ball a is released from rest when it is just touching the cord and drops through the vertical distance h a 5 8 in. before striking ball b. assuming e 5 0.9 and no friction, determine the resulting maximum vertical displacement h b of the ball b

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

What organization and environment is described above?
