You are using a rope to pull a 15 kg suitcase along a level path. There is friction between the suitcase and the floor, so you must pull with some difficulty to get the suitcase moving, needing a force of about 120N. Afterward, you find that by maintaining that force, the suitcase acceleration while sliding along the floor, the coefficient of static friction is 0.81and the coefficient of kinetic friction is 0.40.

a. Draw a force diagram and label all the forces on the suitcase for the static situation.

b. Draw a force diagram and label all the forces on the suitcase for the kinetic situation.

c. Explain the differences between your two force diagrams in part A and part B.

d. Find the acceleration that the suitcase experiences while you're dragging it across the floor.

e. How would your answer to part D change if you decided to add 5kg worth of items to the suitcase?

Question: You try to pull a 400-N crate along a horizontal surface by tying a rope around it and pulling upward on the rope at an angle of 30° above the horizontal. Knowing that the force you have to exert on the rope to keep the crate moving with constant velocity is 188 N. a/ Draw the free body diagram and compute the coefficient of kinetic friction between the crate and the surface. b/ Is this easier or harder than...

A 3.3 kg object is pulled by 4 ropes. One rope is used to pull the object 15° North of East with a force of 25 N. A second rope pulls it due south with a force of 15 N. A third pulls the object 22° west of north with a 36 N magnitude. If the object is moving due west with a constant acceleration (a=1.0 m/s^2 ), describe the force (magnitude and direction) applied by the 4th rope.

A stuntman whose mass is 76 kg swings from the end of a 3.5-m-long rope along the arc of a vertical circle. Assuming that he starts from rest when the rope is horizontal, find the magnitudes of the tensions in the rope that are required to make him follow his circular path at each of the following points. (a) at the beginning of his motion (b) at a height of 1.5 m above the bottom of the circular arc (c)...

You use a rope of length ℓ to tie the front of a 1500-kg truck to the rear of a 1000-kg car and then use an identical rope of length ℓ to tie the front of the car to the rear of a 500 kg trailer. Each rope will break if its tension exceeds 1200 N . You attach a strong cable to the rear of the truck and use a winch to pull it with a force of magnitude...

A factory worker pushes a 32.0 kg crate a distance of 4.3 m along a level floor at constant velocity by pushing downward at an angle of 29 ? below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. part a. What magnitude of force must the worker apply to move the crate at constant velocity? (N) part b. How much work is done on the crate by this force when the crate is pushed...

An automobile having a mass of 1100 kg initially moves along a level highway at 110 km/h relative to the highway. It then climbs a hill whose crest is 80 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill. Let g = 9.81 m/s2. For the automobile, determine its change in kinetic energy and its change in...

A worker pushed a 21 kg block 8.0 m along a level floor at constant speed with a force directed 30° below the horizontal. If the coefficient of kinetic friction between block and floor was 0.30, what were (a) the work done by the worker's force and (b) the increase in thermal energy of the block-floor system?

A 0.726-kg rope 2.00 meters long lies on a floor. You grasp one end of the rope and begin lifting it upward with a constant speed of 0.710 m/s. Find the position and velocity of the rope’s center of mass from the time you begin lifting the rope to the time the last piece of rope lifts off the floor. Plot your results. (Assume the rope occupies negligible volume directly below the point where it is being lifted.)

Using a rope that will snap if the tension in it exceeds 387 N, you need to lower a bundle of old roofing material weighing 449 N from a point 6.1 m above the ground. Obviously if you hang the bundle on the rope, it will snap. So, you allow the bundle to accelerate downward. (a) What magnitude of the bundle's acceleration will put the rope on the verge of snapping? T-mg = -ma Why are most of the solutions...
