The FIGURE 1 below shows the angular velocity versus time graph of a wheel. Figure 1 \( 2.1 \) Convert \( 2 \mathrm{rev} / \mathrm{s} \) into \( \mathrm{rad} / \mathrm{s} \). 2.2 Use the graph (without using kinematics equations) to calculate: 2.2.1 The particle's angular position at \( 4 \mathrm{~s} \). 2.2.2 The particle's angular acceleration at \( 2 \mathrm{~s} \).
