I’m stuck on a problem involving a cord that has mass. I know how to do problems where the cord's mass is 0 but ones the factor of the cords mass is introduced I’m lost.(adsbygoogle = window.adsbygoogle || []).push({});

I’m stuck on the following problem:

A block (mass m1) on a smooth horizontal surface, connected by a cord that passes over a pulley to a second block (mass m2), which hangs vertically.

Determine a formula for the acceleration of the system if the cord has non-negligible mass mc specify in terms of L1 and L2 the lengths of cord from the respective masses to the pulley (total cord length L =L1+L2)

How do I approach this problem?

The answer (if it helps) is a=(m2+mc(L2/L))g/(m1+m2+mc)

Any help will be highly appreciated.

Thanks
