Just wanted to ask why is it that for isobaric processes, when we wanted to find Q, sometimes we use Q = nCpΔT and sometimes we use Q = nCvΔT + p(Vf - Vi)?
How do we determine which should be used and when?
I see, would it be correct to write
\frac{1}{2}(4M)(\frac{3}{4}v_{0})^{2} = \frac{1}{2}(k)(x)^{2} + \frac{1}{2}(5M)(V1^{2})
If it is then what method should I use to find v1?
Homework Statement
A mass 3M moving horizontally with velocity v_{0} on a frictionless surface, strikes head-on and sticks to a horizontal spring system of natural length l and spring constant k with masses M at each end. The spring has negligible mass.
