A 41.0-kg child swings in a swing supported by two chains, each 3.04 m long. The tension in each chain at the lowest point is 348 N. (a) Find the child's speed at the lowest point. m/s (b) Find the force exerted by the seat on the child at the lowest point. (Ignore the mass of the seat.) N (upward)

light rope of length 1.40 m is attached to the ceiling.A small steel ball with mass 0.200 kg swings on the lower end of therope as a pendulum. As the ball swings back and forth, the angle u betweenthe rope and the vertical direction has a maximum value of 37.0°.(a) What is the tension in the rope when θ = 37.0°? (b) What is the tensionwhen θ = 25.0°?

In the figure, point A is pin support and point B has a sliding support. Find the reaction forces at points A and B. 20 N 4 N/m 53° 2 N/m В 6 m 2 m 3 m

A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with μk=μk= 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its acceleration.

A hungry bear weighing 730 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 5.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. Goodies Q (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) When the bear is at x = 1.16 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.16 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positiv direction is upward. Include the sign of the value in your answer.) Fx N N (c) If the wire can withstand a maximum tension of 775 N, what is the maximum distance the bear can walk before the wire breaks? m

An object is subjected to three forces as shown in the figure.  Assume F1 = 50.0 N and F2 = 95.0 N, what is T if the object is in static equilibrium?  Enter a number with three significant digits.

2. A helicopter drops a cable which is attached to a load. The cable is partially reeled in, and the helicopter flies east. Air resistance causes the load to swing backwards such that it makes an angle of 20.0° with the vertical. Draw a FBD of the situation.

Two identical, side-by-side springs with spring constant 240 N/m support a 2.00 kg hanging box. Each spring supports the same weight. By how much is each spring stretched?

An ornament of mass 40.6 g is attached to a vertical ideal spring with a force constant (spring constant) of 45.6 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch?

What's the force on each rope if the person is standing 1.75 m from one end?
