PHY 101 Circular Motion Objective Question

Question

If a wheel with a radius of 0.5 m has an angular acceleration of 4 rad/s², what is the magnitude of the tangential acceleration of a point on its rim?
Options
A 8 m/s²
B 2 m/s²
Correct Answer
C 4.5 m/s²
D 0.125 m/s²
Correct Answer

Option B is the correct answer.

Detailed Explanation

Tangential acceleration is given by aT = αR. Therefore, aT = (4 rad/s²) * (0.5 m) = 2 m/s².

Hint

This is a direct application of the formula relating tangential and angular acceleration.
