A solid weights 260N in air, 240N in water of a fluid density 1000kg/m^3, and 250N in oil
Determine the relative density of the solid and of the oil
I think I have already worked out the density of the solid:
Weight of water displaced = 260N - 240N = 20N
20N / 9.8 = 2.0408kg
Water density...
Also, calculating work done during the acceleration:
This is force x distance, however would the force I use be the force determined previously (the tractive effort)?
Thank you for any help!
I have a question here which involves a car of mass 2100kg going up a slope of 1 in 10, accelerating from 7m/s to 11m/s, through a distance 145m. There is also frictional resistance of 1.7kn. Essentially I would like someone to run through what I've done and offer any assistance if possible...
