A box is sitting on a flat turntable that is spinning at 1 rpm (top view shown below); the box is r=756 mm away from the axis of rotation O and does not slip at this speed. The coefficients of static and kinetic frictions between the box and the table are 0.76 and 0.10 respectively. If the table starts to accelerate at 10x0.76 rad/s², calculate the critical angular speed of the turntable when the box begins to slip. Give your answer in rpm, rounded to one decimal place. r W,a of A
