Answer to Question #193170 in Physics for eloy

Question

In a pinball game, after you start the game with the pinball you can only control two levers. At one point in the game, you decide to “catch” the pinball with the lever and stop it. The lever is at an angle of 20.1°. Then you roll down the pinball with a constant velocity at an angle of 14.3°. What are the coefficients of static friction and kinetic friction? Draw the free-body diagram for both cases

how can y solve this

Answer 1

$$\mu_s=\tan 20.1=0.366\\\mu_k=\tan 14.3=0.255$$
