The speed of a pulse traveling along the cord, v = 19.8 m/s.
The tension, T on the cod is first obtained as follows:
T = 2.0 * 9.8 m/s²
T = 9.6 N
The mass per unit length, μ of the cord is then determined:
μ = 0.3/6
μ = 0.05 kg/m
The speed of the pulse, v = √(T/μ)
v = √(9.6/0.05)
v = 19.8 m/s
In conclusion, the speed of the pulse is the distance covered per unit time.
