A mechanic pushes a 2672 kg car from rest to a speed of v, doing 5045 J of work in the process. During this time, the car moves 37m. Neglecting friction between the car and the road, find v.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

Awave has a wavelength of 7 mm and a frequency of 19 hertz. what is its speed?
