ES At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 2.25 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 2.0 cm and each unit on the vertical axis is 2.0 cm. y pulse 1 - - - - - X C - - - - - - pulse 2 (a) At what location will the resultant of the two pulses have minimum amplitude? cm (b) At what time will the resultant of the two pulses have minimum amplitude?
