Here is the answer for the question – **1. A turntable has a moment of inertia of 3.0 102 kgm2 and spins freely on a frictionless bearing at 25 rev/min. A 0.30-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.10 m from the center. By what factor does the kinetic energy of the system change after the putty is dropped onto the turntable?**. You’ll find the correct answer below

### 1. A turntable has a moment of inertia of 3.0 102 kgm2 and spins freely on a frictionless bearing at 25 rev/min. A 0.30-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.10 m from the center. By what factor does the kinetic energy of the system change after the putty is dropped onto the turntable?

**The Correct Answer is**

**0.91**

### Reason Explained

0.91 is correct for 1. A turntable has a moment of inertia of 3.0 102 kgm2 and spins freely on a frictionless bearing at 25 rev/min. A 0.30-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.10 m from the center. By what factor does the kinetic energy of the system change after the putty is dropped onto the turntable?
