A small block on a frictionless, horizontal surface has a mass of 2.40x10-2 kg . It is attached to a massless cord passing through a hole in the surface (Figure 1). The block is originally revolving at a distance of 0.300 m from the hole with an angular speed of 2.39 rad/s. The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.150 m. Model the block as a particle. Figure...

A Review Part A The 11 lb block is originally at rest on the smooth surface. It is acted upon by a radial force of 2 lb and a horizontal force of 7 lb, always directed at 30 from the tangent to the path as shown. Determine the time required to break the cord, which requires a tension T-30 lb. Neglect the size of the block for the calculation. (Figure 1) Express your answer with the appropriate units. Value Units...
