If two bodies contact one another without slipping, and the points in contact move along different paths, then the normal components of acceleration of the points will be the same. O True O False

In the figure, block 1 has mass m1 = 440 g, block 2 has mass m2 = 520 g, and the pulley is on a frictionless horizontal axle and has radius R = 4.9 cm. When released from rest, block 2 falls 72 cm in 5.4 s without the cord slipping on the pulley. (a) What is the magnitude of the acceleration of the blocks? What are (b) tension T2 (the tension force on the block 2) and (c) tension T1 (the tension force on the block 1)? (d) What is the magnitude of the pulley’s angular acceleration? (e) What is its rotational inertia? Caution: Try to avoid rounding off answers along the way to the solution. Use g = 9.81 m/s2.

Shown below are top-down views of three blocks on rotating turntables. The turntables rotate in the same amount of time, and the blocks are rotating with the turntables, not sliding. The masses of the blocks and their distances from the centers are given. Rank the blocks from most force holding it on the turntable to least. B R=2 cm m 5 kg R=3 cm = 4 kg R 5 cm m=1 kg
