Homework SourseA 22 kg block is pulled across a horizontal surface by a rop
A 22 kg block is pulled across a horizontal surface by a rope. The block has an acceleration of 1.6 m/s2 and the coefficient of kinetic friction is 0.19. Determine the tension in the rope
Solution
T - f = ma ;
T = f +ma ;
T = N + ma ;
T = mg + ma ;
T = m ( g + a ) ;
T = 22 ( 0.19 * 9.8 + 1.6 ) ;
T = 76.16 N <------ans
