Question

100 gram ball connected to one end of a 30cm Wireless cord and another end of the cord is connected with fixed rotational axis . what is the moment of inertia with respect to the axis​
Fine...Wbu?​

Answer 1

Answer:

0.009 kg/m²

Step-by-step explanation:

Moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of each particle with its square of a distance from the axis of rotation.

The moment of inertia, I=mr²

Step I> Identify the given information

              Mass of the ball = 100 grams

              Length of the cord = 30 cm

             Convert the given measurements

               Grams to kilograms

              100 grams = 100 ×\frac{1}{1000} = 0.1 kg =100×10001=0.1kg

              Centimeters to meters  

               30 cm = 30 ×\frac{1}{100} = 0.3 m 30cm=30×1001=0.3m

Step II> Calculate the moment of inertia

              The moment of inertia I=mr²

                     I=(0.1kg)(0.3m)²

                     I = (0.1 kg)(0.09) m²

                     I = 0.009 kg.m²

Hence, moment of inertia of the ball I=0.009 kg.m² [Ans]
