A block of mass \( 10 \mathrm{~kg} \), moving in \( x \) direction with constant speed of \( 10 \mathrm{~ms}^{-1} \), is subject to a retarding force \( F=0.1 \times \mathrm{J} / \mathrm{m} \) during its travel from \( x=20 \mathrm{~m} \) to \( 30 \mathrm{~m} \). Its final \( K E \) will behttps://bit.ly/YTAI_PWAP https://www.pw.live
