The lawn roller has a mass of 80 kg and a radius of gyration KG 0.175 m. If it is pushed forward with a force of 200 N when the handle is at 45, determine its angular acceleration. The coefficients of static and kinetic friction between the ground and the roller are = 0.12 and = 0.1, respectively. = 200 mm 23 200 N
