12) A horizontal circular platform rotates counterclockwise about its axis at the rateo with a mass of 69.3 kg, walk clockwise around the platform along its edge at the speed of 1.15 m/s with respect to the platform. Your 20.7-kg po at half the platform's radius and at half your linear speed with respect to the platform. Your 17.9-kg mutt, on the other hand, sits still on the platform at a position that is 3/4 of the platform's radius from...

A Texas cockroach of mass 0.17 kg runs counterclockwise around the rim of a lazy Susan (a circular disk mounted on a vertical axle) that has radius 15 cm, rotational inertia 4.9 ✕ 10−3 kg · m2, and frictionless bearings. The cockroach's speed (relative to the ground) is 2.0 m/s, and the lazy Susan turns clockwise with angular speed ω0 = 2.9 rad/s. The cockroach finds a bread crumb on the rim and, of course, stops. (a) What is the...
The reel shown in Figure P10.70 has radius R and moment of inertia I. One end of the block of mass m is connected to a spring of force constant k and the other end is fastened to a cord wrapped around the reel. The reel axle and the incline are frictionless. The reel is wound counterclockwise so that the spring stretches a distance d from its unstretched position and is then released from rest. (a) Find the angular speed...
A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.913 rad/s. You, with a mass of 69.5 kg, walk clockwise around the platform along its edge at the speed of 1.05 m/s with respect to the platform. Your 20.5-kg poodle also walks clockwise around the platform, but along a circle at half the platform\'s radius and at half your linear speed with respect to the platform. Your 17.9-kg mutt, on the other hand, sits still on...
