A pulse can be described as a single wave disturbance that moves through a medium. Consider a pulse that is defined at time t =
0.00 s by the equation y(x) = 6.00 m³/(x² + 2.00 m²) centered around x = 0.00 m. The pulse moves with a velocity of v = 3.00 m/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 = 5.00 s?
1) If the object changes directions with the same speed, it will be changing its velocity, because velocity is a vector, which depends on both magnitude and direction. Speed is just magnitude regardless of direction.
