The 10.0-lb block rests on a surface for which µk = 0.500. It is acted upon by a radial force of 2.00 lb and a horizontal force of 7.00 lb, always directed at 30.0° from the tangent to the path. As the block is rotating in a circular path, the speed of the block increases and as a result the tension in cord AB also increases. If the block is initially moving in a circular path with a speed v1 = 2.00 ft/s at the instant the forces are applied, (A) determine the speed of the block when the tension becomes 20.0 Ib and (B) determine the time required for the tension to be 20.0 lb.
