Document Summary
Values of all required constants will be provided on nal exam. Choose the one alternative that best completes the statement or answers the question: two particles, a and b, are in uniform circular motion about a common center. The acceleration of particle a is 3. 2 times that of particle b. The period of particle b is 2. 0 times the period of particle a. The ratio of the radius of the motion of particle a to that of particle b is closest to: 1. 60, 0. 64, 0. 625, 1. 25, 0. 80. A 2. 0 kg ball is suspended by two wires from a horizontal arm, which is attached to a vertical shaft, as shown. A 2. 5 kg, sliding on a rough surface, has a speed of 1. 2 m/s when it makes contact with a spring. The block comes to a momentary halt when the compression of the spring is 5. 0 cm.
