Learning Goal: To use normal and tangential coordinates to determine the magnitude of the acceleration of a block moving in circular motion. The block shown in (Figure 1) rests on the disk at a distance r = 31 cm from the center. Initially, the block and disk are at rest. If the disk begins to rotate with an angular acceleration of a = 2.9 rad/s², at what time does the block begin to slip? The coefficient of static friction is μ = 0.32 and the mass of the block is m = 0.8 kg. Figure EST < 1 of 1 Part D What is the maximum tangential velocity of the block?
