6. A pendulum that consists of a ball (m = 1.50 kg) attached to a light cord rotates in a circular path of
radius r = 0.800 m at constant speed v, as shown in Figure. Here the angle 0 = 65°, and we ignore air
friction and assume the mass of the light cord is negligible.
(a) Calculate the tension T in the cord.
= L.
(b) Calculate the centripetal force acting on the ball.
= 'd
(c) Calculate the velocity v of this uniform circular motion.
Answers:
A 1.5-lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed
of 10.6 ft/sec as it passes position B, determine (a) the magnitude N of the force exerted by the fixed rod on the slider and (b) the rate v
at which the speed of the slider is changing (positive if speeding up, negative if slowing down). Assume that friction is negligible.
