The circular disc has a mass of 5 kg and radius 1 m.A bowling ball of mass M and radius Ris at rest on the floor of a stationary train car. rere is sufficient friction between the ball and the floor such that the ball will roll without Slipping. If the train begins to accelerate forward with acceleration a relative to the earth, determine the linear acceleration (magnitude and direction) of the bowling ball as seen from a. A passenger on the train b. A person at rest relative to the earth.
- Conservation of Angular Momentum. A uniform spherical asteroid rotates around an axis through its CM. Over time, it accretes space dust (of the same density), whose initial velocity with respect to the asteroid’s CM is zero. The asteroid grows from mass m0 to m. How does the period of its rotation change with m? If the asteroid doubles in mass, how and by what factor does its period of rotation change?r:0.3m →F= 100 N The uniform disk is infrally at rest and has a mass of 24 kg, Is momesit of inertia about its mass center isgiven by S=tmr A 100 N fconstant) forde Falts pon it as shawn and it ralls withoutslip on the horizontal surfuce.
