Homework Statement On a fixed frictionless horizontal rail is a massless ring to which is attached a bob of mass 'm' hanging vertically downwards with an inelastic and inextensible string. Starting from rest the ring is given a constant a constant horizontal acceleration (g/\sqrt{3})...

hey tim thanks 4 the replyo:) this is exactly what i thought! but i have gr8 respect for the authors, probably they implied a different orientation of the disc say xz plane(if we assume table to be xy) and the particle travels along y axis or something else like that and they failed to...

Homework Statement This question I came across in mechanics book by Bostock Chandler > A uniform disc, resting on a smooth horizontal table, has mass 'm', radius 'a' and centre C. A particle of mass 'm', moving across the table with speed 'v', strikes a point A on the...

Q1. ADIABATIC FREE EXPANSION(unrestricted and free) in vacuum gas a volume of gas is released expected expansion proceeds withouut change in internal energy therefore temperature is contant (joule's law) . there is no pressure acting on this system threfore no work is done...
