b) Consider the case where the angle 0 is 16.8° and the penguin is not moving relative to the ground. Using Newton's Second Law of Motion [and the free-body diagram from part (a)], determine the force of friction on the penguin. Note that the solution for the force of friction should be written in unit vector notation using the rotated coordinate system. Assume the mass of the penguin is 5.11 kg and that g = 9.81 m/s?. Answer in units of N with 3 sig figs. Hint: force of friction, f; µs N, as this expression gives us the maximum force of static friction that is possible, not necessarily the force of friction that is present.

A particle, which remains at rest, is acted on by three forces, P, Q and R, and no others, as shown in the diagram attached. The force P acts horizontally to the left, the force Q acts vertically upwards and the force R acts downwards and to the right at an angle of 30◦ to the horizontal. The magnitude of P is 52 N.

A mysterious force acts on all particles along a particular line and always points towards a particular point P on the line. The magnitude of the force on a particle increases as the cube of the distance from that point, that is, F∝ r3, if the distance from the P to the position of the particle is r. It has been determined that the constant of proportionality is 0.23 N/m3, i.e. the magnitude of the force on a particle can be written as 0.23r3, when the particle is at a distance r from the force center. Find the magnitude of the potential energy, in joules, of a particle subjected to this force when the particle is at a distance 0.21 m from point P assuming the potential energy to be zero when the particle is at P.

A massless spring with spring constant 26 N/m hangs vertically. A body of mass 1.0 kg is attached to its free end and then released. Assume that the spring was unstretched before the body was released. Find how far below the initial position the body descends. I don't understand why I'm getting this first part wrong specifically because the formula is just x= mg/k because F=kx.
