The notes are listed in order of increasing frequency, and the tensions given are for a D'Addario EXL110 string set. The guitar is held vertically with the headstock and tuning pegs up, main body down. Suppose that instead of being attached to the bridge of the guitar, each string is attached to a mass such that that gravity acting on the mass produces the same tension in the string as above. What is the total mass in kilograms, that the guitar strings together support

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

What are two different ways you could find the value of a? explain these methods.
