A block of mass \( m \) in \( 1.4 \mathrm{~kg} \) is attached to a string that is wrapped around the circumierence of a wheel of tadius \( R= \) \( 9.0 \mathrm{~cm} \). The wheel rotates freely about its axis and the string Part A wrops oround its circumference without slipping. Initidly the Find the moment af inertia of the wheel if the block rises to a height of \( h=7.9 \mathrm{~cm} \) pefore momentarfy coming to iest Wheel rotates with an angular speed 4 , causing the block to tise with a linear speed \( e=0.28 \mathrm{~m} / \mathrm{s} \) (Fiqure 1)
