A 0.448 kg bead can slide on a
curved wire as seen in the figure.
Assume h1 = 4.87 m and h2 = 2.00 m. If the wire is frictionless and the bead is released with an initial speed of 1.75 m/s in the forward direction then find the speed of the bead at B.

A 40-kg child slides down a curved slide starting at the top with an initial speed of 4 m/s. (a) Suppose that the slide is frictionless. Determine the speed of the child when she is 3 m below her starting height. (b) Suppose that the slide has friction. Determine the speed of the child when she is 5 m below her starting height if she starts from rest and 300 J of thermal energy is dissipated during the motion.
