ΣF = 0
at freebody of mass 3
ΣF = 0
T - W3 = 0
T - 25.4 = 0
T = 25.4 Newtons
at freebody of mass 2
ΣF = 0
T + N - W2 = 0
25. 4 + N - 33.3 = 0
N = 7.9 Newtons
at freebody of mass 1
ΣF = 0
N' - N - W1 = 0
N' - 7.9 - 49.5 = 0
N' = 57.4 N

The drawing shows box 1 resting on a table, with box 2 resting on top of box 1. A massless rope passes over a massless, frictionless pulley. One end of the rope is connected to box 2, and the other end is connected to box 3. The weights of the three boxes are W_1 = 52.8 N, W_2 = 3.1 N, and W_3 = 25.8 N. Determine the magnitude of the normal force that the table exerts on box 1.

A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of +17.2 m/s in a time of 26.3 s. The combined mass of the boat and trailer is 479 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?

A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of +16.8 m/s in a time of 29.5 s. The combined mass of the boat and trailer is 413 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?

Box A weighs 80 N and rests on a table (Figure 4-30). A rope that connects boxes A and B drapes over a pulley so that box B hangs above the table, as shown in the figure. The pulley and rope are massless, and the pulley is frictionless. What force does the table exert on box A if box B weighs (a) 35 N; (b) 70 N; (c) 90 N? 64.

QUESTION 7 A box is at rest on a horizontal, frictionless table. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 6.75 m/s. Force F3 is also horizontal; it has magnitude 2.85F, and acts at an angle 22.6° to the direction of F1. If forces F1 and F3 act on the box at the same time, find the magnitude...

2. A box (M-8.5 kg) sits on a table (box #1). Another box (m=6.3 kg) sits on a ramp at an angle of e= 30° (box #2). The boxes are connected to each other with a cable and pulley, as shown in the diagram to the right. The static coefficient of friction between box #1 and the table is 0.88, and the kinetic coefficient is 0.81. There is no friction between box # 2 and the ramp. (4 pts.) Draw...
