4. A string attached to a wall makes an angle of 35° with the vertical and is connected to a knot. Another string from this knot is holding a mass m.

2. Mass m₁ slides without friction on a plane inclined at 40° above horizontal plane. It is attached to a second mass m₂ by a light string. If m₁ = 5kg, m₂ = 4kg, determine the acceleration of each block and the tension of the string.

4.A basket of food weighing 500 N is suspended at the end of a uniform rod 3.5 m long of mass 4.0 kg. A cable is connected to the center of the rod and has an angle 40 degrees with respect to the horizontal. A bear of mass 220 kg walks on the rod and tries to reach the food basket. a) Draw a free body diagram of the rod. b) If the maximum tension of the cable is 3800 N, where is the bear on the rod when the cable breaks? c) find the force that the wall on the rod right before the cable breaks. wall K 40⁰ Cable bear [/// & food basket

8. An object is pulled across a rough horizontal surface with an applied force of 300 N [40o below the horizontal]. The applied force is slowly rotated down toward the horizontal, decreasing the 40o angle. What will happen to the force of friction acting on the object and the acceleration? a. Both increase.b. Both decrease.c. Friction decreases and acceleration increases.d. Friction increases and acceleration decreases.e. None of the above statements are accurate.

2. A 25 kg crate hangs in equilibrium from two strings made from the same material and knotted together as shown. 30° 45° Determine the tension in each of the cables. Note that the tension will be different in each cable.

Q4) The Great Valerio is performing his high wire act. He stands on a (massless wire) exactly in the middle of two posts a distance d = 50.1 m apart. The wire buckles under his weight and he ends up h = 1.25 m below the vertical location where %3D the wire is attached to the posts. Valerio has a mass of my= = 73.5 kg. What is the tension of the wire ? h d/2 d/2 E
