At a playground, a 19-kg child plays on a slide that descends a total of 2.3 meters (vertically). The child starts out at rest at the top of the slide. During the child’s descent, friction does -361 J of work on the child. What speed does the child have at the bottom of the slide?

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.
