(choose chapter or problem)

A 100 g bead slides along a frictionless wire with the parabolic shape y = 12 m-1 2x2 . a. Find an expression for ay, the vertical component of acceleration, in terms of x, vx, and ax. Hint: Use the basic definitions of velocity and acceleration. b. Suppose the bead is released at some negative value of x and has a speed of 2.3 m/s as it passes through the lowest point of the parabola. What is the net force on the bead at this instant?
