4 Two Boxes Are Connected By A Weightless Cord Running Over A Very Light Fric Tionless Pulley As Shown In The Figure 1 (70.96 KiB) Viewed 42 times

4. Two boxes are connected by a weightless cord running over a very light fric- tionless pulley as shown in the figure. Box 1, of mass 19 kg, is initially at rest on the top of the table. The box and table have a coefficient of kinetic friction of 0.29. Box 2 has a mass of 17 kg, and the system begins to move just after it is released from rest. The box starts at 49 cm above the floor and eventually reaches the floor. a) Calculate the velocity upon impact with the floor b) Calculate the acceleration of each box. c) What is the tension in the cord? m2
