Answer:
a. v = 13.572 m / s
b. T = 2.578 x 10 ⁻³ N
Explanation:
μ = 1.9 x 10 ⁻⁴ kg / m
y = y ₙ * sin ( kx + wt )
a.
y = 0.034 m * sin ( 2.8 m⁻¹) x + (38 s⁻¹)t
R = 2.8 m⁻¹
W = 38 s⁻¹
To determine speed of the string
v = W / R = 38 / 2.8
v = 13.572 m / s
b.
v = √ T / μ
v ² = T / μ
To determine the tension on the string
T = v ² * μ
T = 13.572 m/s * 1.9 x 10 ⁻⁴ kg / m
T = 2.578 x 10 ⁻³ N
