Part 2) A transverse wave is described by the equation: y(x. 1) = A sin(kx-ct + 4) + yo cm. The graph below shows the vertical position (in cm) versus horizontal position (in cm) at f = 0's as the transverse wave travels along a rope. Use this figure to determine the amplitude, wave number, and phase angle/shift for the wave. Give numeric answers for this part. 2 y Axis 2 5 6 7 x Axis A= cm K= rad/cm rad Part 3) Determine the speed of the wave if the angular frequency is 2.1 rad/s. Speed = cm/sPart 1) 20 Displacement (m) AAA -10 -15 -20 15 20 Time (s) A mass oscillates on the end of a spring. The position versus time graph is shown above. Which of the following graphs correctly show the velocity vs time of the same mass? green blue greenblack AN Part 2) Using Hooke's law, calculate the force exerted by the spring at / = 17 s. The mass is m = 1.20 kg and the spring constant is k = 1.71 N/m. F = N upwards Note: enter a negative number if the force is downwards. Part 3) What is the speed of the mass at this time? Hint: It is a good idea to consider the energy stored in the spring to solve this. m/s
