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 F.

a- What is the acceleration of the three-vehicle system in terms of F, where F is in N?

Express your answer in terms of F.

b- What is the maximum pulling force you can exert on the truck before a rope breaks?

Express your answer with the appropriate units.

c- If you now attach the cable to the front of the trailer and again pull the system, what is the maximum force with which you can pull it without snapping a rope?

Express your answer with the appropriate units.

You are on roller blades, holding a rope attached to a truck. Starting from rest, the truck pulls you. After traveling for 7.33 s, you are moving at 10.0 m/s. If the friction in your roller blades is negligible, what is the tension in the rope? Your mass is 69.0 kg. Report your answer in SI units, rounded to the nearest whole number.

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...

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.)

Two students use a uniform slab of wood (mass= 10 Kg, length = 2.0m) in order to move a delicate but heavy piece of lab equipment (mass = 55 kg). The piece of equipment is placed 0.35 m from one of the students (note: one of the students is stronger than the other, but they succeed in keeping the slab perfectly level). Find the force that the student nearest to the load applies to the slab:
