Problem 8: Two wave pulses are moving toward each other, as shown in the figure. Pulse 1 moves at a speed of v = 0.17 m/s to the left, while pulse 2 moves to the right at 2 a speed of v2 = 0.22 m/s. Their initial peak-to-peak separation is d = 2.65 m. 1 1 -d- Part (a) After what time interval, At, in seconds, will the peaks of the pulses meet? Numeric : A numeric value is expected and not an expression. At = Part (b) If the amplitude of pulse 1 is A1 = 3.36 cm and that of pulse 2 is A2 = 1.51 cm, what is the amplitude, in centimeters, after the elapse of time interval At when the two pulses meet? Numeric : A numeric value is expected and not an expression. A = Part (c) Using the amplitudes A, = 3.36 cm and A2 = 1.51 cm, what would be the amplitude, in centimeters, after the elapse of time interval At (when they meet) if pulse 2 were inverted? Numeric : A numeric value is expected and not an expression. A = Part (d) What will be the velocity of pulse 2 once it passes completely through pulse 1? MultipleChoice : 1) It will double in value. 2) The pulses stick together after the collision, so the velocity will be an average of the initial velocities. 3) It will be zero. 4) It will have the same speed but opposite direction. 5) It will be half its original value. 6) There is not enough information. 7) It will remain the same.
