Question

As shown in the figure, a 10-kg block on a perfectly smooth horizontal table is connected by a horizontal string to a 63-kg block that is hanging over the edge of the table. What is the magnitude of the acceleration of the 10-kg block when the other block is gently released? 8.5m/s/s 8.1 m/s/s I 7.5m/s/s 9.0m/s/s Three boxes rest side-by-side on a smooth, horizontal floor. Their masses are 5.0 kg, 3.0 kg, and 2.0 kg, with the 3.0-kg mass in the center. A force of 50 N pushes on the 5.0-kg box, which pushes against the other two boxes. What magnitude force does the 5.0-kg box exert on the 3.0-kg box? 0N 10N 25N 40N A 10.0-kg picture is held in place by two wires, the first one hanging at 50.0 to the left of the vertical and the second one at 45.0degree to the right of the vertical. What is the tension in the first wire? 69.6N 50.8N 98.IN 69.4N
