Math Problem Statement
Two blocks connected by a rope of negligible mass are being dragged by a force at a 29° angle above horizontal (see figure below), so that the blocks are already moving to the right. Suppose F = 67.0 N, m1 = 10.0 kg, m2 = 26.0 kg, and the coefficient of kinetic friction between each block and the surface is 0.136. Use g=9.8 m/s2. 5-p-047 (b) Determine the acceleration of the system.
Correct: Your answer is correct. m/s2
(c) Determine the tension T in the rope.
Incorrect: Your answer is incorrect. N

Formulas
Net Force: F_net = F_horizontal - f_k
Acceleration: a = F_net / (m1 + m2)
Friction Force: f_k = μ_k * N
Normal Force: N = (m1 + m2)g - F_vertical
Vertical Component of Force: F_vertical = F * sin(θ)
Horizontal Component of Force: F_horizontal = F * cos(θ)
