"A small block, with a mass of 250 g, starts from rest at the top of a ramp. It then slides without friction down the incline, around the loop at the bottom and then onto the final level section.
The maximum height of the incline is 80 cm, and the radius of the loop is 15 cm."

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

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
