Shown above is a time sequence of a mass moving horizontally on a frictionless surface attached to a spring. The mass bounces back and forth between extremes of x=+3 and x=-3 in sequence A through G. An arrow next to the mass shows the direction of travel at each time. The time steps are not necessarily equal between each frame. If more than one time could satisfy the condition, answer the FIRST time that the condition occurs. 1. At which time does the mass have the largest velocity? 2. At which time is the tension in the spring the greatest? 3. At which time does the mass have the smallest speed? 4. At which time is the tension in the spring the least? This is known as the equilibrium position. 5. At which point is the acceleration the greatest? The least? 6. At which point is the kinetic energy the greatest? The least? 7. Suppose t=0 at point A. What is the phase angle of this system? A. zero B. pi/2 C. pi D. 3pi/2 E. Could be anything 8. Over which interval does the mass complete 1 complete "cycle"? (This is like one compelte trip around a circle or 2pi radians) 9. Over which interval does the mass complete half a cycle? (pi radians).
