The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is ini- tially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.

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?

Nitrogen at 100 kpa and 25∘c in a rigid vessel is heated until its pressure is 260 kpa. calculate the work done and the heat transferred during this process, in kj/kg. for the nitrogen, cv= 0.743 kj/kg⋅k at room temperature. (round the final answers to one decimal place.)the work done during this process is (kj/kg)? the heat transferred during this process is (kj/kg)?
