Question

The linear acceleration of a car is 10m/s². If the wheels of the car have a diameter of 1m, the angular acceleration of the wheels will be

• A. 10 rad/sec²
• B. 20 rad/sec²
• C. 1 rad/sec²
• D. 2 rad/sec²

Answer 1

Answer: (B)

20 rad/sec²

Answer 2

$\text{Angular acceleration} = \frac{\text{linear acceleration}}{\text{radius}}$ $= \frac{10}{0.5}$

$= 20rad/sec^{2}$
