A mass m is placed at the rim of a frictionless hemispherical bowl with a radius R and released from
rest as in (Figure 1). It then slides down and undergoes a
perfectly elastic collision with a second mass 3m sitting
at rest at the bottom of the bowl.

A. What is the speed of the first mass just after the collision?

B. What is the speed of the second after the collision?

C. To what maximum height will the first travel after collision.

(All answers in terms of g, m,R)

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1
