A block is at rest on the incline shown in the figure. The coefficients of static and kinetic friction are s = 0.81 and k = 0.69, respectively. The acceleration of gravity is 9.8 m/s. 18 kg 36 What is the frictional force acting on the 18 kg mass? Answer in units of N. part 2 of 3 What is the largest angle which the incline can have so that the mass does not slide down the incline? Answer in units of . part 3 of 3 What is the acceleration of the block down the incline if the angle of the incline is 42? Answer in units of m/s.
