A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28° incline (Fig. 4–75). After sliding down the 110-m-long incline (on which the coefficient of kinetic friction is uk = 0.18), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which uk = 0.15) and comes to rest after a distance x. Use Newton's second law to find the snowboarder's accel- eration while on the incline and while on the flat surface. Then use these accelerations to determinex. 5.0 m/s 110 m Uk = 0.18 %3D 28°/ Hk = 0.15 FIGURE 4–75 Problem 92.
