A textbook of mass 1.90kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.150m , to a hanging book with mass 2.93kg . The system is released from rest, and the books are observed to move a distance 1.22m over a time interval of 0.790s .
Part A What is the tension in the part of the cord attached to the textbook?
Part B What is the tension in the part of the cord attached to the book?
Part C What is the moment of inertia of the pulley about its rotation axis?

At one instant a bicyclist is 28 m due east of a park's flagpole, going due south with a speed of 8 m/s. after that, 11 s later, the cyclist is 65 m due north of flagpole, going due east with a speed of 10 m/s.
find the velocity of their center of mass before the collision.
A speedboat moving at 33.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of ?3.20 m/s2 by reducing the throttle. (a) How long does it take the boat to reach the buoy? (b)What is the velocit..
