Attached to the rope of length R = 0.5m, the object with mass m = 1kg is rotated clockwise in a vertical plane. Object; The linear speed is 2m / s when it is at point A in the first second, and when the linear speed is 8m / s when it is at point B in the second second, the theta = 127 degrees between A and B is swept.

a) Calculate the tensile forces on the rope while the object is at A and B points.

b) Calculate the total acceleration vectorially when the object is at point A.

(g=10m/s^2, sin37=0.6 and cos37=0.8)
