analysis\n1. what if we replaced the cart in experiment 1 with a friction tray? how could we use this setup to compute the coefficient of kinetic friction between the tray and the track? please give your answer in 2 - 4 concise, well thought out sentences. you may wish to consider equations 5 & 6 with the friction force properly included to help you answer this question. (5 pts.)\n\n2. was it difficult to find the proper mass that achieved translational equilibrium in experiment 2? how would friction affect your results? assume the system was in perfect equilibrium but the pulley and/or the track had friction; how would this affect the velocity of the cart as it rolled up the track? how about down the track? please answer these questions collectively in 2 - 4 well written sentences. (5 pts.)\n\n3. in experiment 3, if we had known masses m1 and m2 but we added an unknown mass to the cart, could we use this setup to determine the unknown mass? please explain your answer. (5 pts.)\n\nconclusion\nwrite a few sentences here summarizing this laboratory experiment in the context of the physical laws that govern two objects connected by a string and pulley system. (5 pts.)

Answer

Brief Explanations:

The Bent Knee Bolster stretch targets the hip flexor group, and the Iliacus is a key hip flexor muscle that is stretched in this position. The Rectus Femoris is a quadriceps muscle stretched in different knee - extension focused stretches, the Tensor Fasciae Latae and IT Band are connective tissue structures targeted by side - focused stretches, not this specific bent - knee hip stretch.

Answer:

D. Iliacus
