A small blob of putty of mass m = 90.0 g falls from the ceiling and lands on the outer rim of a turntable of radius R = 15.0 cm and moment of inertia I = 1.90E-2 kg·m2 that is rotating freely with angular speed 3.77 rad/s about its vertical fixed-symmetry axis. What is the postcollision angular speed of the turntable-putty?
