1.A block accelerates at 3.1 m/s2 down a plane inclined at an angle 24.0◦. Find μk between the block and the in- clined plane. T
he acceleration of gravity is 9.81 m/s2 . 2.A 1200 kg car moves along a horizontal road at speed v0 = 20.1 m/s. The road is wet, so the static friction coefficient between the tires and the road is only μs = 0.189 and the kinetic friction coefficient is even lower, μk = 0.1323. The acceleration of gravity is 9.8 m/s2 . What is the shortest possible stopping dis- tance for the car under such conditions? Use g = 9.8 m/s2 and neglect the reaction time of the driver. Answer in units of m. Thank you for the help!
