c) Next consider the case where the angle 0 is 40.2° and the penguin is sliding down the hill. Using Newton's Second Law of Motion, determine the acceleration of the penguin. Note that the solution for acceleration should be written in unit vector notation using the rotated coordinate system. Assume that the mass of the penguin is 5.11 kg and that g = 9.81 m/s². Answer in units of m/s² with 3 sig figs.

Question
Transcribed Image Text:A penguin of mass, m, is on an inclined surface (hill), as shown in the diagram. The inclined surface is at
an angle of 0 from the flat ground. The coefficient of static friction, µs = 0.498 and the coefficient of
kinetic friction, H; = 0.295. Also assume there is a force from gravity (i.e. the weight, W = mg, is pointed
straight down towards the ground, as always).
