A loaded penguin sled weighing 67.0 N rests on a plane inclined at angle θ = 22.0° to the horizontal (see the figure). Between the sled and the plane, the coefficient of static friction is 0.230, and the coefficient of kinetic friction is 0.170. (a) What is the minimum magnitude of the force F→, parallel to the plane, that will prevent the sled from slipping down the plane? (b) What is the minimum magnitude F that will start the sled moving up the plane? (c) What

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
