Section 2.6 Motion on an Inclined Plane 26. || A skier is gliding along at 3.0 this on horizontal, frictionless snow. He suddenly starts down a 10 incline. His speed at the bottom is 15 rat's. a. What is the length of the incline? b. How long does it take him to reach the bottom? 37. Il Particles A, B, and C move along the x-axis. Particle C has an initial velocity of 10 m/s. In FIGURE P2.37, the graph for A is a position-versus-time graph; the graph for B is a velocity-versus- time graph; the graph for C is an acceleration-versus-time graph. Find each particle's velocity at t = 7.0 s. x (m) v. (m/s) Particle B 30+ 30- 20 20 10 - 10 - 0 -1 (s) -10 8 -10 2 4 6 8 1 (s) -20- -20- -30- -30 ax (m/s?)
