A pulse can be described as a single wave disturbance that moves through a medium. consider a pulse that is defined at time t=0.00s by the equation y(x)=6.00m3x2+2.00m2 centered around x=0.00m. the pulse moves with a velocity of v=3.00m/s in the positive x-direction. (a) what is the amplitude of the pulse? (b) what is the equation of the pulse as a function of position and time? (c) where is the pulse centered at time t=5.00s?
