Express your answer to two significant figures and include appropriate units. Value Units My Answers Give Up Part B What is the minimum coefficient of static friction required to keep the mugfrom sliding? Express your answer to two significant figures, Figure 1 of 1 Submit My Answers Give Up 0,27 79 Wed 3:28 PM Help Close previous l 4 of 6 l next Provide Feedback ContinueExplanation / Answer
m = 0.27 kg , g = 9.8 m/s^2
(a) for rest mug Net force along horizontal direction is zero
f = mgsin(theta)
f = 0.27*9.8*sin(17)
friction force f = 0.77 N
(b) Net force along vertical direction
N = mgcos(17)
f = u*N
0.774 = u*0.27*9.8*cos(17)
u =0.31
