ADDITIONAL PROBLEMS Question 4.5a: The figure shows two blocks of wood connected by a light string. The first block has mass m, = 4.00 kg and the second block has mass m, = 1.60 kg. A constant horizontal force of magnitude P = 14.0 N acts on the first block and both blocks are sliding to the right. The coefficient of kinetic friction between each block and the horizontal surface is HK = 0.100. Determine the magnitude of the tension T in the string connecting the blocks. Question 4.5b: Two blocks with masses m, = 6.00 kg and m, = 7.10 kg are connected by a light string, as in the figure. Mass m, is descending and mass m, is moving to the right across a horizontal surface with a coefficient of kinetic friction given by u, = 0.170. m, Determine the acceleration a of m, and the magnitude T of the tension in the string. m/s2 a = T = Need Help?
