Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_16

3/16 Determine the initial acceleration of the 15-kg block if (a) \( T = 23 \text{ N} \) and (b) \( T = 26 \text{ N} \). The system is initially at rest with no slack in the cable, and the mass and friction of the pulleys are negligible. Given in the diagram for PROBLEM 3/16: - Mass of the block, \( m = 15 \text{ kg} \) - Static friction coefficient, \( \mu_s = 0.50 \) - Kinetic friction coefficient, \( \mu_k = 0.40 \) - Applied force \( T \) is at an angle of \( 30^\circ \) relative to the horizontal.
