Two Masses Are Connected by a Cord That Passes Over

Question 82

Multiple Choice

Two masses are connected by a cord that passes over a pulley as shown in the figure. The pulley and the cord have negligible mass and m2 (6.0 kg) moves on a horizontal surface with a coefficient of static friction of 0.5, while m1 (2.0 kg) is suspended vertically. If the masses start from rest, what is the acceleration of m2? Two masses are connected by a cord that passes over a pulley as shown in the figure.
