Logan, Cassie and Abbey are doing the Pulse Speed Lab. Logan and Cassie stand 6.8 m apart and stretch a zinc-coiled Snakey between them. Logan introduces a pulse into the Snakey at his end. Using a stopwatch, Abbey measures that it takes 15.1 seconds for the pulse to travel to Cassie's end and back two times. They then repeat the experiment with a copper-coiled Snakey stretched the same distance and find that pulses travel back and forth two times in 16.9 seconds.
a. Determine the speed of the pulse in the zinc-coiled Snakey.
b. Determine the speed of the pulse in the copper-coiled Snakey.
