Block a of Mass 8

question 27

Multiple Choice

Block A of mass 8.0 kg and block X are attached to a rope that passes over a pulley.A 50-N force P is applied horizontally to block A,keeping it in contact with a rough vertical face.The coefficients of static and kinetic friction between the wall and block A are μ_s = 0.40 and μ_k = 0.30.The pulley is light and frictionless.In the figure,the mass of block X is adjusted until block A descends at constant velocity of 4.75 cm/s when it is set into motion.What is the mass of block X?

• A)6.5 kg
• B)7.2 kg
• C)8.0 kg
• D)8.8 kg
