A uniform solid block of mass 5kg has a square base of side 20cm and height 40cm. It is placed on a horizontal turntable at a distance of 50cm from the center (measured to the center of the block's base). One of the base edges is perpendicular the radius. The coefficient of static friction is 0.6. As the turntable slowly spins up, determine if the block will slide or topple first. (Take g=10m/s2)
