A 75-kg snowboarder has an initial velocity of 5.0 m/s at
Chapter 4, Problem 92GP(choose chapter or problem)
A 75-kg snowboarder has an initial velocity of \(5.0 \mathrm{\ m} / \mathrm{s}\) at the top of a \(28^{\circ}\) incline (Fig. 4–75). After sliding down the 110-m-long incline (on which the coefficient of kinetic friction is \(\mu_{k}=0.18\), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which \(\mu_{k}=0.15\)) and comes to rest after a distance x. Use Newton’s second law to find the snowboarder’s acceleration while on the incline and while on the flat surface. Then use these accelerations to determine x.
