help me those question Question 4.5a:The figure shows two blocks of wood connected by a light string. The first block has mass m,= 5.80 kg and the second block has mass m,= 2.20 kg. A constanthorizontal force of magnitude P = 24.0 N acts on the first block and both blocks are sliding to the right. The coefficient of kinetic friction between each block andthe horizontal surface isHK= 0.100.m2Determine the magnitude of the tension T in the string connecting the blocks.Question 4.5b:Two blocks with masses m,= 5.50 kg and m,7.60 kg are connected by a light string, as in the figure. Mass m, is descending and mass m, is moving to theright across a horizontal surface with a coefficient of kinetic friction given by µ,= 0.170.m,m2Determine the acceleration a of m, and the magnitude T of the tension in the string.m/s²a =T =
