The motion of a 4-lb block B in a horizontal plane is defined by the relations r
Question:
The motion of a 4-lb block B in a horizontal plane is defined by the relations r = 3t2 ? t3 and ? = 2t2 , where r is expressed in feet, t in seconds, and ? in radians. Determine the radial and transverse components of the force exerted on the block when(a) t = 0,(b) t = 1s.
