016 (part 1 of 3) 10.0 points A block is at rest on the incline shown in the figure. The coefficients of static and ki- netic friction are s = 0.45 and k = 0.38, respectively. The acceleration of gravity is 9.8 m/s². 20 kg μl 21° What is the frictional force acting on the 20 kg mass? Answer in units of N. 017 (part 2 of 3) 10.0 points What is the largest angle which the incline can have so that the mass does not slide down the incline? Answer in units of º 018 (part 3 of 3) 10.0 points What is the acceleration of the block down the incline if the angle of the incline is 30° ? Answer in units of m/s².
