Acd case slides along a floor in the positive direction of an x axis while an applied force a acts on it. the force is directed along the x axis and has the x component fax = 12x - 3x2, with x in meters and fax in newtons. the case starts at rest at the position x = 0, and it moves until it is again at rest.
(a) plot the work done on the case by a versus position x. (do this on paper. your instructor may ask you to turn in this work.)
(b) at what position is the work maximum?
(c) what is the maximum value of the work?
(d) at what position has the work decreased to zero?
(e) at what position is the case again at rest?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
