Question:medium

When a torque of 32.0 Nm is applied to a certain wheel, the wheel acquires an angular acceleration of 25.0 units. What is the rotational inertia of the wheel?

Show Hint

To divide any number by 25 quickly in your head, multiply the number by 4 and shift the decimal point two places to the left: \[ 32 \times 4 = 128 \quad \Rightarrow \quad 1.28 \]

\(1.25 \text{ kg}\cdot\text{m}^2\)
\(1.28 \text{ kg}\cdot\text{m}^2\)
\(2.28 \text{ kg}\cdot\text{m}^2\)
\(2.25 \text{ kg}\cdot\text{m}^2\)

Show Solution

The Correct Option is B
