To give a 22-kg child a ride, two teenagers pull on a 3.5- kg sled with ropes, as indicated in the figure (Figure 1). Both teenagers pull with a force of 55 N at an angle of 35° relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. You may want to review (Pages 134 - 136) . Part A Find the acceleration of the sled and child. Express your answer using two significant figures. ΑΣφ a = m/s² Submit Roguoct Apewor

There are two images, one has the question information and the other is the question.

Two weights are hanging from the ceiling of an elevator as shown in (Figure 1). Find the tension in cable A when the elevator is not moving. Express your answer in newtons. Find the tension in cable B when the elevator is not moving. Express your answer in newtons. Find the tension in cable B when the elevator is accelerating downward at 1.4 m/s2. Express your answer in newtons. Find the tension in cable A when the elevator is accelerating downward at 1.4 m/s2. Express your answer in newtons.

In Figure 1, we depict two boxes and an applied force of magnitude 100.0N. The horizontal floor is frictionless, and box A is more massive thanbox B. Which of the following is correct? (Before you answer this question, draw FBDs and sum forces.)a. Box A pushes on box B with a force of 100 N, and box B pusheson box A with a force of 100 N.b. Box A pushes on box B harder than box B pushes on box A.c. Boxes A and B push on each other with equal forces of less than 100.0N.d. The boxes will not begin to move unless the total weight of the twoboxes is less than 100.0 N.

a) On an interstate highway in a rural region of Wyoming, a car is traveling at a speed of 38.0 m/s. Is the driver ?exceeding the speed limit of 75.0 mi/h b) What if the driver were from outside the United States and is familiar with speeds measured in kilometres per hour? What is the speed of the carin ?km/h

A concrete statue of a banana is hung from two ropes, as shown below. The right-side rope has a tension of 230 Newtons. What is the mass of the concrete banana? (Take the center of mass of the banana to be its horizontal midpoint.) 0.53 m 0.15 m 1.75 m

The pulley system shown in the figure (Figure 1) is used to lift a 52-kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. The crate is rising with an acceleration of 2.6 m/s2. a) Assuming the masses of the chains, pulleys, and ropes are negligible, determine the magnitude of the force F→. b) Determine the tension in the upper chain. c) Determine the tension in the lower chain.

When a 60 kg skier first starts to be pulled up the ski hill by an old school T-bar, she undergoes a constant acceleration of 1.8 m/s2 during the first few seconds of the pull.  The applied force from the T-bar is directed 40 degrees above a line that is parallel to the surface of the hill  The incline of the hill is 19 degrees above the horizon, as can be seen by alpha in the figure below.  Assume that the positive X direction is directed up the hill and the positive y direction is directed away from the surface of the hill and that the coefficient of dynamic friction between the skiis and the snow is 0.1.  a) What is the magnitude of the applied force (FApp) in Newtons (N) required from the T-bar when the skier first starts to be pulled up the hill with a constant acceleration of 1.8 m/s2?  b) What is the magnitude of the normal force between the skier and the snow in Newtons (N) in the scenario described above (skier is being pulled up the hill by the T-bar with a constant…

Two identical 20.0-kg balls, each 25.3 cm in diameter, are suspended by two 35.0-cm wires as shown in the figure (Figure 1). The entire apparatus is supported by a single 18.0-cm wire, and the surfaces of the balls are perfectly smooth. Find the tension in the top wire. Find the tension in each of two bottom wires.

A child decides to take her cat on a walk, but the cat does not cooperate.  The child pulls on the 2.5 kg cat with force of 20 N in a direction that is 30 degrees above horizontal, and the cat resists being pulled forward with a horizontal force of 15 N.   How much force is the child pulling with in the horizontal direction (the direction the cat will move)?
