At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 1.82 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 5.0 cm and each unit on the vertical axis is 4.0 cm. y (cm) pulse 2 x (cm) pulse 1 (a) At what location and time will the midpoint of pulse 1 coincide with the leading edge of pulse 2? location time cm S (b) What is the y-value of the resultant wave at the time and location determined in part (a)? cm (c) At what location and time will the midpoint of pulse 1 coincide with the midpoint of pulse 2? location time cm S (d) What is the y-value of the resultant wave at the time and location determined in part (c)? cm
