Imagine a planet where gravity mysteriously acts tangent to the equator and in the eastward directioninstead of radially inward. Would this force do work on an object moving on the earth? What is the sign ofthe work, and does it depend on the path taken? Explain by using the work integral and provide a sketch ofthe force and displacement vectors. Provide quantitative examples.
If a force does zero net work on an object over a closed loop, does that guarantee the force is conservative? Explain with an example or counterexample
A futuristic amusement ride spins riders in a horizontal circle of radius 5 m at a constant speed. Thefloor drops away, leaving riders pinned to the wall by friction (coefficient µ = 0.4). What minimum speedensures they don’t slip, given g = 10 m/s²? Draw diagram (or a few) showing all forces, thevelocity of the rider, and their acceleration
