Please write (a,b, or c) before you write the answer so i know which is which

thanks

A block of mass M is a rest on the surface of an incline at a distance of h = 10 cm above the base (the height of the incline is H = 50 cm). The coefficient of static friction between the block and the plane is 0.85 and theta = 15. Draw the free body diagram for the block of mass M. Write down Newton's 2nd law along the two mutually perpendicular directions in your free body diagram. If the whole assembly is rotated about the vertical axis as shown in the diagram above, what is the maximum angular velocity, omega. at which the block will not slip? (1.764142)

Explanation / Answer

c.) mw^2/r= mgsin(theta)+u(mgcos(theta))

w^2/(H-h(tan(15)))= g(sin(15))+0.85(g*cos(15))

w^2= 1.134

w= 1.065 rad/sec
