A horizontal 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).
