Question 13 [8] A baseball player slides to 3rd base. A friction force (1) acts against his motion as indicated in the figure. He needs to slide a distance d of 2.5 m to be safe. (a) Use the work-energy theorem with non-conservative forces to write down an equation to find the actual distance the player slides. (b) If he starts sliding with an initial velocity of 5.0 m/s and the coefficient of kinetic friction between himself and the dirt is 0.6, how far does the player slide, and does he make it to base safely? (c) How long did he slide for? (Hint: use one of the kinematic equations.
