A 76 kg person is being pulled away from a burning building as shown in figure. If the tensions in the two ropes when the person is momentarily motionless are equal T1=T2 and one of the two angels shown in figure is 30 degrees. a) find the other angle b) calculate the tension in the rope

A 89.0 kg person is being pulled away from a burning building as shown in the figure below. -10° (a) Calculate the tension (in N) in the first rope, T₁, if the person is momentarily motionless. (Enter the magnitude only.) N (b) Calculate the tension (in N) in the second rope, T₂, if the person is momentarily motionless. (Enter the magnitude only.) N

The figure below shows a hanging mass m = 9.1 kg.  Determine the Tension T1.

A 2 m long massless rod supports a 12 N weight.  The left end of each rod is held in place by a frictionless pin.  In each case, a vertical force F is holding the rods and the weights at rest.  Rank the magnitude of the vertical force F applied to the rods.  Example A B  If two cases are equal they can go in either order.

Problem 3: Two children push horizontally on a third child who is sitting fixed in a wagon that has essentially frictionless wheels. The first child pushes in the positive x-direction with force of magnitude 70 N while the second child pushes in the negative x-direction with a force of magnitude 95 N. a) Draw a free-body diagram of the "child-in-the-wagon" system. b) If the child in the wagon has a mass of 40 kg and the wagon has a mass of 9 kg, what is the acceleration of the child in the wagon?

Multiple part question: A worker in a factory slides a heavy box up a ramp into a truck. The box has a mass of 84 kg, and the ramp is 3 m long and makes an angle of 34° with the horizontal. The coefficient of friction between the box and ramp is 0.6. What is the weight of the box? What is the normal force acting on the box? What is the force of friction acting on the box?   Assuming the worker pushes the box up the ramp with a constant velocity, how much work does the factory worker do on the box in order to get it into the truck?   How much gravitational potential energy does the box have once it reaches the top of the ramp?

A truck in trouble is pulled on a level road by applying three forces as shown in this figure. The forces are F₁ = 1600 lb and F₂ = 500 lb. Magnitude and direction of force F3 are yet to be determined. The resultant of the forces is R = 2500 lb along the x-axis to the right. Determine the magnitude of F3 and the angle made by F3 with the x-axis. F2 'F₂ 30° F1 F3 What is the y-component of force F1? O 1.500 lb. O2. 1600 lb. 3.zero lb. 4

A block having a mass of m = 10.5 kg is suspended via two cables as shown in the figure. The angles shown in the figure are as follows: a = 11° and ẞ=25°. We will label the tension in Cable 1 as 7, and the tension in Cable 2 as T2. What is T2 Cable 1 Cable 2- B m

Two children pull a third child on a toboggan. Assuming that they pull on ropes that are parallel to the ground determine the magnitude of the force exerted on the toboggan.
