Ahorizontal pull p pulls two wagons over a horizontal frictionless floor, as shown in the gure. the tension in the light horizontal rope connecting the wagons is a. equal to p, by newton's third law. b. equal to 2000 n. c. greater than p. d. less than p.

where u is in radians. The linear velocity of the point is tangent to the circle; the point’s linear speed v is given by v vr (radian measure), (10-18) wherev is the angular speed (in radians per second) of the body. The linear acceleration of the point has both tangential and radial components.The tangential component is at ar (radian measure), (10-22) where a is the magnitude of the angular acceleration (in radians per second-squared) of the body.The radial component of is (radian measure). (10-23) If the point moves in uniform circular motion, the period T of the motion for the point and the body is (radian measure).
