IP A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the O student-stool system is 5.0kg m2.A second student tosses a 2.0 kg mass with a speed of 2.8 m/s to the student on the stool, who catches it at a distance of 0.50 m from the axis of rotation. stay the same decrease O increase My Answers Give Up Correct Part B Calculate the initial kinetic energy of the system Express vour answer using two significant fiqures. 4.0 +(1.7.352)27-4 + 1.7 . .352)ω
