Grade Problem 4: The block is originally at rest and held by a string (cord), which is fixed at the point O as shown below, on the horizontal smooth surface (no friction). A horizontal force FI=80 N is applied at the block in the tangent direction, and a radial force F2= 15 N is also applied to the block at the same time. The radius is r= 15 m. After the block starts moving in the circular path under the given force, determine: (a) the speed of the block. (b) the acceleration of the block, and (c) the force in the spring (cord) (25 points) 1 NTI
