in my opinion both of your temperatures should be in °K, and P2 should be in absolute value, as your P1

i re-calculated everything and now stuck on the last one, i tried the link u provided, actually over there they have both the accelerations without and with friction, but in this example we have only 1..

its rad/s^2, that was a typing mistake that was a typing mistake as well. thnx a lot 4 ur help, yaa i am trying on that.

2nd formula i guess. S= ut + 1/2 at^2 a = 2S/t^2 = 0.44m/s^2 is it ok now? if yes, what you think about rest of the calculation?

i did it that way, bcaz given velocity is in /1.5s, so i do need to convert it in m/s we can't use V = Vo + at, as a is still not calculated... am i right?

1. A mass of 0.5 kg suspended from a flywheel, if the mass is released from rest and falls a distance of .5m in 1.5s calculate a) the linear acceleration of the mass b) the angular acceleration of the wheel c) the tension in the rope d) the frictional torque, resisting motion mass of wheel...

thnx a lot guyz... :D

1. if the magnetic flux linking all the turns of a 50 turn coil changes from 10 mWB to 20 mWB and induces an e.m.f. of 62.5 V in the coil, calculate the time over which the flux changes. i know the formula to calculate the flux which is E = -N change in flux / change in time. to...
