Answer:
2 seconds
Explanation:
v = at + v₀
19.62 m/s = (9.81 m/s²) t + 0 m/s
t = 2 s
Answer:
18.7842493212 W
Explanation:
T = Tension = 1871 N
= Linear density = 3.9 g/m
y = Amplitude = 3.1 mm
= Angular frequency = 1203 rad/s
Average rate of energy transfer is given by

The average rate at which energy is transported by the wave to the opposite end of the cord is 18.7842493212 W
