A racquet ball with mass m = 0.241 kg is moving toward the wall at v = 13.7 m/s and at an angle of θ = 34° with respect to the horizontal.

What characteristic does a good conductor possess? 1. Outer electrons of elements in good conductors are loosely held and are able to migrate readily. 2. Outer electrons of elements in good conductors are held tightly and are able to migrate readily.

An apparatus similar to the one used in lab uses an oscillating motor at one end to vibrate a long rope with frequency f = 40 Hz and amplitude A = 0.25 m. The rope is held at constant tension by hanging a mass on the other end.
