Shown to the right is a block of mass m = 9.2 kg sitting on a ramp that makes an angle 0 = 25 with the horizontal. This block is being pushed by a horizontal force F = 220 N. The coefficient of kinetic friction between the two surfaces is u=0.47. m 50% Part (a) Write an equation for the acceleration of the block up the ramp using variables from the problem statement together with g for the acceleration due to gravity. a= (F cos(0) mg sin(0) - (mg cos(0) + F sin(0))/ml 1^4 5 6 1 2 3 HOME Grade Summary Deductions Potential Submissions 96% Attempts remaining: 2 (4% per attempt) detailed view cos(a) cos() cos(0) () 789 sin(a) sin() sin(0) Y e d F +0 1 END g m n VO BACKSPACE DEL CLEAR Submit Hint Feedback I give up!
