4. The hanging mobile pictured above consists of two masses, m1 and m2, suspended from a uniform 10 cm long rod, which is in turn suspended from the ceiling at an angle of 70° as pictured above. The mass m, is 0.02 kg, while the mass of the rod is m, = 0.01 kg. Assuming the mobile is in a state of static equilibrium, find the value of mass m2. 10 cm 70° 4 cm 110°

11. The diagram below shows a ladder that is 6.0 m long and has a mass of 20.0 kg. The ladder rests on a level floor and against a wall at an angle of 15° to the wall. The coefficient of static friction between the ladder and the floor is 0.232. A person with a mass of 60.0 kg begins to climb the ladder. The base of the ladder will begin to slide away from the wall when the person reaches which distance interval from the base of the ladder? A. 0 m–1.5 mB. 1.5 m–3.0 mC. 3.0 m–4.5 mD. 4.5 m–6.0 m

How do you do this? A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see figure below). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of ? = 60.0°. The basket weighs 80.0 N. a) When the bear is at x = 1.00 m, find the tension (in N) in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam. b) If the wire can withstand a maximum tension of 875 N, what is the maximum distance (in m) the bear can walk before the wire breaks?

2. Use the equilibrium conditions to find the weights w1, w2, and w; required to balance the mobile. Hint: start from the bottom rung and apply the conditions for equilibrium, then work your way up. 4 cm 8 cm 5 cm 1 cm W3 2 cm 4 cm w2 W1 0.5 N

As shown in the diagram below, a 234 g uniform meter stick is supported horizontally by two vertical strings.     Determine the tension in the left string & the tension in the right string.left string tension = right string tension =

2. A bag of cement of Mass 45 kg hangs from three wires as shown in figure. Two of the wires make angles 01=60° and 02=30° with the horizontal. If the system is in equilibrium, find the tensions T1, T2 in the wires. CEMENT

A 3.0-m -long ladder, as shown in (Figure 1), leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.50.
