A stretched string fixed at each end has a mass of 48.0 g and a length of 8.80 m. The tension in the string is 51.0 N. (a) Determine the positions of the nodes and antinodes for the third harmonic. (Enter your answers from smallest to largest distance from one end of the string.) nodes: 0 2.9 5.9 8.8 antinodes: 1.5 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m m EEEE m Need Help? (b) What is the vibration frequency for this harmonic? Hz Read It Watch It

An automobile having a mass of 1,000 kg is driven into a brick wall in a safety test. The bumper behaves like a spring with constant 4.15 x 106 N/m and is compressed 3.15 cm as the car is brought to rest. What was the speed of the car before impact, assuming no energy is lost in the collision with the wall? m/s Need Help? Read It Watch It
