A wheel starting from rest is uniformly ...

A wheel starting from rest is uniformly accelerated at `4rad//s^(2)` for `10s`. It is allowed to rotated uniformly for the next 10 s and is finally brought to rest in the next 10 s. Find the total angle rotated by the wheel.

To solve the problem step by step, we will break it down into three phases of motion: uniform acceleration, uniform motion, and uniform deceleration. ### Step 1: Uniform Acceleration 1. **Given Data**: - Initial angular velocity, \( \omega_0 = 0 \, \text{rad/s} \) (starting from rest) - Angular acceleration, \( \alpha = 4 \, \text{rad/s}^2 \) - Time, \( t_1 = 10 \, \text{s} \) ...
