Chapter 3, Problem 3/354

(choose chapter or problem)

A 1.8-lb particle P is given an initial velocity v0 1 ft/sec at the position 0 and subsequently slides along the circular path of radius r 1.5 ft. A drag force of magnitude kv acts in the direction opposite to the velocity. If the drag parameter k 0.2 lb-sec/ft, determine and plot the particle speed v and the normal force N exerted on the particle by the surface as functions of over the range . Determine the maximum values of v and N and the values of at which these maxima occur. Neglect friction between the particle and the circular surface. 3/354
