Hello,

Can someone please show how to solve parts a b and c please?

Thank you

3) (Treat as an "energy" problem) While exploring an abandoned barn, Lobster got stuck in a crate down a shaft. Luckily the (massless, frictionless) pulley system is intact. Frog's plan to rescue its friend consists of jumping up to the end of the rope, which it can just barely reach, and using its weight to hoist Lobster up. Unfortunately, h<D, and mF < mi; yet, luckily, Frog has unlimited amounts of candy to snack on. So, Frog succeeds in rescuing Lobster. m m O m mF h 3 mc - m₁ Treat this as a 1D problem for each. (a) Frog, without eating any candy, just jumps up to hold on to the loose end of the rope; what happens next? (Use words.) (b) In your own words, for the complete, successful plan, describe the motion(s), and describe a suitable system for each motion. (c) Which are the potential and kinetic energies of both Frog and Lobster just before the moment that Frog returns to the ledge? (d) How many pieces of candy (each with mass m) does Frog need to eat to bring Lobster up to the upper floor level? (e) Will this plan work for all values of h? Yes/No, and give an explanation.
