A 6.09 kg box is pulled to the right with a force of 68.0 N. If the force of friction is 37.6 N, what is the net force in the horizontal direction?

A 853 N magician (note: this is weight, not mass) is freeing himself from some shackles while suspended above a swimming pool filled with alligators.  Two ropes are suspending the magician.  The left rope makes an angle of 42 above the horizontal and points up and to the left.  The right rope makes an angle of 78 above the horizontal and points up and to the right.  Calculate the tension in the left rope, in N. (Please answer to the fourth decimal place - i.e 10.5432)

A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.0 degrees above the horizontal. What is the x-component of his pulling force?

Four forces act on an object, given by A = 47.3 N east, B = 37.3 N north, C = 78.7 N west, and D = 80.7 N south. (Assume east and north are directed along the +x-axis and +y-axis,respectively.)   (a) What is the magnitude of the net force (in N) on the object?   (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.) ° counterclockwise from the +x-axis

Four forces act on an object, given by  A = 38.3 N east, B = 45.3 N north, C = 70.7 N west, and D = 88.7 N south.  (Assume east and north are directed along the +x-axis and +y-axis, respectively.) (a) What is the magnitude of the net force (in N) on the object?   (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)

A horizontal force of 430 N is applied to a stationary wooden box in one direction, and a 700 N horizontal force is applied in the opposite direction. What additional force is needed for the box to remain stationary?

The figure below shows a bird feeder that weighs 189.7 N. The feeder is supported by a vertical string, which is in turn tied to two strings, each of which is attached to a horizontal branch. The left string makes a 60° angle with the branch, while the right string makes a 30° angle. What is the tension in each string (in N)? left string right string bottom string 60° Bird food 30° N N

You are pulling a 72-kg box at a constant speed of 7.4 m/s. If you're pulling the rope with a force of 300 N at an angle of 37° measured above the horizontal, what is the coefficient of friction between the box and the ground?

A person is trying to judge whether a picture (mass = 1.47 kg) is properly positioned by temporarily pressing it against a wall. The pressing force is perpendicular to the wall. The coefficient of static friction between the picture and the wall is 0.750. What is the minimum amount of pressing force that must be used?
