Problem 2: The potential energy for a particular two-dimensional force field is given by
V(x, y) = Axe-ky, where the constants A and k are chosen for dimensional consistency.
(a) Choose specific (and reasonable) values for A and k, and use Mathematica, Desmos, or
the equivalent to plot contours of constant potential energy for various energy levels,
over a region of the plane centered on the origin.
(b) Show that an infinitesimal displacement along an equipotential line has the form
dr
dr = dr x + ŷ.
kx
(c) Find the expression for the force field, and plot this vector field over the same region
of the plane (and with the same choice of constants) as in part (a).

- Use vectors to explain why it is difficult to hold a heavy stack of books perfectly still for a long period of time. As you become exhausted, what eventually happens? What does this mean in terms of the forces acting on the books?arrow_forwardA circular log floating in water is neutrally buoyant. Our ancestors found that by having half a log with semi-circular cross section and hollowing out the interior, it became stable so that they could use it to migrate across oceans. The reasons for it to become stable are: (i) (ii) (iii) (iv) It lowers the centre of gravity G so that it is below the centre of buoyancy B. It lowers the centre of gravity G so that it is below the metacentre M. It increases the metacentric radius BM. It enables the shifting of the centre of buoyancy B laterally to produce a restoring moment when it is tilted.

- The largest animal is found in sea as it requires no energy to support its weight by using hydrostatic principle. However bird has to support its own weight by using Bernoulli principle to create pressure difference while in flight. Bird cannot be very large and there are also fewer species of large bird than small bird. The reasons are: (i) (ii) There is less food in the air than in the sea. The bone structure of the bird has to be light and it is structurally more difficult to maintain the strength to weight ratio as the bird becomes larger. The lift and drag on a bird is due to viscous and pressure forces. They are surface forces proportional to the length square while the weight of a bird due to gravity is proportional to the length cube. At large length scale, length square is much smaller than length cube and it becomes difficult to generate lift to support a bird in flight.

If the gravitational force of the earth decreases, the most likely scenario(s) is (are): (1) (11) The iceberg will have a larger portion exposed above the sea level since its weight will be lower.
