FIGURE 8-2 Swimmers at a water park have a choice of two frictionless water slides (see Figure 8-2). Although both slides drop over the same height, h, slide 1 is straight while slide 2 is curved, dropping quickly at first and then leveling out. How does the speed v1 of a swimmer reaching the end of slide 1 compares with v2, the speed of a swimmer reaching the end of slide 2?

FIGURE 8-4 An object of mass 2 kg is held at the top of a triangular wedge as shown in Figure 8-4, and then released. The reference level for potential energy is at the base of the triangle. Neglect friction and use g = 10 m/s2.Refer to Figure 8-4. What is the kinetic energy of the object at the top of the wedge?
