To solve the problem step by step, we will follow the principles of rotational motion and use the relevant equations. ### Step 1: Understand the given data - The wheel covers an angular displacement of \( \theta = 50 \) revolutions in \( t = 5 \) seconds. - The initial angular velocity \( \omega_0 = 0 \) (since the wheel starts from rest). ### Step 2: Convert revolutions to radians Since angular displacement in physics is typically measured in radians, we need to convert revolutions to radians: ...
