Question text
The motion of a wave traveling along a stretched string is described by the equation:
y(x,t)=(8.5cm)sin(5.2x−7.2t)
where x is in metres and tt is in seconds.
What is the minimum time it takes for a particle on the string to move from y = -8.5 cm to y = 8.5 cm?
Homework Answers
Here angular frequency w = 7.2 s^-1
Minimum time = time taken to reach from maximum to minimum = T/2 = [2pi/w]/2 = pi/w = pi/7.2 = 0.436 s answer
