Question

A 60.0-cm radius disk rotates with a constant angular acceleration of 1.50 rad/s². It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 2.00 rad with the positive x-axis at this time. (a) [25%] Find the angular speed of the wheel at t = 4.00 s (b) [25%] Find the linear velocity of P at t = 4.00 s (c) [25%] Find the linear acceleration of P at t = 4.00 s (d) [25%] Find the angular position (unit in radius) of P at t = 4.00 s.

Step 1

00 \) s. Given: Initial angular velocity, \( \omega_0 = 0 \) rad/s Angular acceleration, \( \alpha = 1.50 \) rad/s\(^2\) Time, \( t = 4.00 \) s Using the equation \( \omega = \omega_0 + \alpha t \), we can calculate the angular speed: \[ \omega = 0 + 1.50 \times Show more…
