1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...

The critical angle is the largest angle for which the gravitational force does not yet cause the block to move. Finding the angle is a problem in which we deal with the block as a particle in equilibrium. Analyze Because the block is an inclined surface, the normal force perpendicular to the surface does not balance the downward force of gravity. The normal force and the force of gravity produce a net force that tends to slide the block down...

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...
