Two balls of unequal mass are hung from two springs that are not identical. the springs stretch the same distance as the two systems reach equilibrium. then both springs are compressed and released. part a which one oscillates faster? which one oscillates faster? the spring with the heavier ball. the spring with the lighter ball. springs oscillate with the same frequency. it is impossible do determine without additional data.

If you go to a nutrition store and buy a supplement, you can count on the fact that it is pure and safe because supplements are regulated, controlled, and inspected by the fda.

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
