Tension is maintained in a string as in the figure. The observed wave speed is 25 m/s
when the suspended mass is 3.5 kg. If the mass per length of the string is 0.05488kg/m, what is the wave speed when the suspended mass is 2.6 kg?

Freya has a mass of 14kg she is running at 1.1m/s to the left when she runs into eric, who is standing still. eric has a mass of 18kg. after the collision, they continue moving together. what is their velocity after the collision. a. 0.48 m/s to the leftb. 2.5 m/s to the leftc. 0.86 m/s to the leftd. 1.4 m/s to the left
