homework 06 – RAHMAN, TARIQUE – Due: Feb 13 2008, 3:00 am 1 Question 1, chap 4, sect 5. part 1 of 1 10 points Consider the following situations. A) An object moves with uniform circular motion. B) An object travels as a projectile in a gravitational ±eld with negligible air re- sistance. C) An object moves in a straight line at con- stant speed. In which of the situations would the object be accelerated? 1. C only 2. A only 3. A and C only 4. B and C only 5. None exhibits acceleration. 6. B only 7. A and B only correct 8. All exhibit acceleration. Explanation: A) The direction of the velocity constantly changes; the centripetal acceleration is di- rected toward the center of the motion. B) The projectile undergoes gratitational acceleration. C) The velocity of the object (its direction and magnitude) is unchanged, so it is not accelerated. Question 2, chap 4, sect 5. part 1 of 1 10 points A satellite of mass M moves in a circular orbit of radius R with constant speed v . True statements about this satellite include which of the following? I) Its angular speed is v R . II) Its tangential acceleration is zero. III) The magnitude of its centripetal accel-
