Physics - NLM Question with Solution | TestHub

A man tows his daughter on a sled on level ice, and she in turn tows behind her a toy sled. The girl and her sled have a combined mass of ${\mathrm{M}}_1$ and the toy sled a mass ${\mathrm{M}}_2$. Dad's tow rope is inclined at an angle $\theta$ to the horizontal. The coefficient of kinetic friction between the sled runners and the ice is $\mu$, and the mass of the ropes is negligible. If the sleds accelerate with acceleration a, derive an expression for the tension in each rope.
