Two massless strings of length L=2 m are attached to a vertical rod at points a distance L= 2.0 m apart. A mass m= 1.5 kg is whirled around the rod as shown. Both strings are taut. The tension in the upper string is measured to be T¡ = 35 N. %3D (a) Draw a force diagram for the mass. (b) Find the tension in the lower string. (c) Calculate the net force on the ball at the instant shown in the figure. (d) What is the speed of the ball?
