Which ball has larger Inertia before touching the ground when it falls freely from a

Answer 1

Answer:

$Mass = 50kg$

Explanation:

Which has the larger inertia

Inertia (I) is calculated as follows:

$I = mr^2$

Where m represents the mass of the object and r represents the distance from the axis.

Take for instance m = 10 and r = 4

The inertia would be:

$I = 10 * 4^2$

$I = 160$

Assume r is constant and m is increased to 25

The inertia becomes:

$I = 25 * 4^2$

$I = 25 * 16$

$I = 400$

Notice that there is an increment in inertia, when the mass increased.

Hence, mass of 50kg will have the larger inertia.
