Chapter 5, Problem 50AP
An 8.40-kg object slides down a fixed, frictionless, inclined plane. Use a computer to determine and tabulate (a) the normal force exerted on the object and (b) its acceleration for a series of incline angles (measured from the horizontal) ranging from 0° to 90° in 5° increments. (c) Plot a graph of the normal force and the acceleration as functions of the incline angle. (d) In the limiting cases of 0° and 90°, are your results consistent with the known behavior?

A trunk with a weight of 250N is at rest on a floor. The coefficients of friction between the trunk and
floor are H=0.200 and Ps=0.350.
a) What is the largest horizontal force that can be applied to the trunk for which the trunk will not move?
(Any force larger than this will start the trunk moving).
b) Once the trunk is moving, what horizontal force is required to keep the trunk moving with a
constant speed?
A 15-pound box sits at rest on a horizontal surface, and there is friction between the box and the surface. One side of the surface is raised slowly to create a ramp. The friction force f opposes the direction of motion and is proportional to the normal force F exerted by the surface on the
box. The proportionality constant is called the coefficient of friction, u. When the angle of the ramp. 0, reaches 25°, the box begins to slide. Find the value of u

- If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position?
