One 3.2-kg paint bucket is hanging by a massless cord from another 3.2-kg paint bucket, also hanging by a massless cord, as shown in Fig. 4-49 (a) If the buckets are at rest, what is the tension in each cord? (b) If the two buckets are pulled upward with an acceleration of 1.25 m/s2by the upper cord, calculate the tension in each cord.

- A 3.00-kg object undergoes an acceleration given by a=(2.00i+5.00j)m/s2. Find (a) the resultant force acting on the object and (b) the magnitude of the resultant force.arrow_forwardA box weighing 66.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end (Fig. 4-37). Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs (a) 30.0 N, (b) 60.0 N, and (c) 90.0 N.arrow_forwardThe 70.0-kg climber in Fig. 4-72 is supported in the “chimney" by the friction forces exerted on his shoes and back. The static coefficients of friction between his shoes and the wall, and between his back and the wall, are 0.80 and 0.60, respectively. What is the minimum normal force he must exert? Assume the walls are ver- tical and that the static friction forces are both at their maximum. Ignore his grip on the rope. FIGURE 4–72 Problem 89.arrow_forward

Each mass is sup- ported by "5-lb test" fishing line which will break when its tension force exceeds 22.2 N (= 5.00 lb). When this device is placed in an elevator, which accelerates upward, only the lines attached to the 2.05 and 2.00 kg masses do not break.

The last climber slips, pulling the second climber off his feet. The first climber is able to hold them both.
