Question:

Pulses A, B, C, and D all travel at 10 m>s on the same string but in opposite directions. The string is depicted at time t = 0 in FIGURE 14-45. The small pulses have an amplitude of 2.0 cm, and the large pulses have an amplitude of 4.0 cm. Find the displacement of point P at times

(a) t = 0.10 s

(b) t = 0.20 s.
