Qin = extra thermal energy the steam has over the milk + heat to be released when the steam condenses
Qout = heat lost from the steam + heat gained by milk
The point at which the automobile leaves the bridge is when it's no longer in contact with the bridge i.e. there is no normal force. There's no force preventing it going through the bridge because it isn't in contact with it.
How would it slip if the linear acceleration smaller than the RHS? I can picture the ball accelerating so quickly that it begins to slip, but not the other way around.
Ahhh, of course. Thank you!
I take it the tangential acceleration is in the direction of the linear velocity? And is the radial acceleration just the centripetal acceleration?
I've just never seen that before.
mgrsin\theta = \frac{7mr^2}{5} \frac{g}{5}
sin\theta = \frac{7r}{25}
Does it want it in terms of r or have I gone wrong?
\theta = sin^{-1}(\frac{7r}{25})
Homework Statement
A uniform solid sphere rolls down an incline without slipping. If the
linear acceleration of the centre of mass of the sphere is 0.2g, then what
is the angle the incline makes with the horizontal? Repeat for a thin
spherical shell.
