PHYS 180 End Material Mini-Test Spring 2010 Put answers on Scantron sheet 4) the body is at rest (B) the body is rotating at a constant angular velocity (which could be zero) the body is not rotating (D) the body has constant (nonzero) angular acceleration (E) the body is undergoing elliptical motion 52. Arigid body is rotating about an axis passing through its center of mass. Every point on the rigid body has the same (A) velocity (B) speed rc@ \D-#Gratiln (E) distance from the axis 53. If a rigid body experience zero net torque, and the moment of inertia decreases, what can we angular velocity and angular rnomentum are constant (C) the angular velocity decreases and the angular momentum is constant (D) the angular momentum increases (E) the angular momentum decreases 54. A mass M is attached to an ideal horizontal spring, whose spring constant is k. We first cause the mass

Unformatted text preview: to oscillate with an amplitude of 2 cm. What happens in the second experiment, compared with the first experiment? (A) The frequency is doubled in the second experiment, compared with the first experiment. (B) The frequency is increased by a factor of r/2 in the second experiment, compared with the in the second experiment. (E) The frequency decreases by a factor of two. 51. Arigid body is in rotational equilibrium. It mustbe true that. .. velocitv increases and the fnst experiment. PHYS 180 Spring 2010 55. What statement(s) are valid about energy in an (undamped) simple harmonic oscillator? I. Kinetic energy is marimum at the turning points II. Kinetic energy is maximum in the middle III. Potential energy is maximum at the tur,ning points IV Potential energy is maxirnum in the middle V. Mechanical energy is a constant in time (A) I and IV only (B) II and III only (C)IIVandVonly @ (E) V only...
