You will need the following items: a rope about 10 to 20 meters long, a meter or yard stick, a watch that records seconds, and a helper. Tie one end of the rope to a doorknob or other secure object at about waist height. Have your helper take one end of the rope and whip it up and down, while you watch. Answer the questions below.
What type of wave was created? How do you know?
Estimate the wavelength of the wave produced.
Estimate the frequency of the wave produced. This is most easily estimated by counting the number of waves that pass the measuring device within a particular time interval as measured on your watch, or by counting the number of times the hand is shaken up and down.
Compute the velocity of your wave.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
