A 12 kg load hangs from one end of a rope that passes over a small frictionless pulley. A 15 kg counterweight is suspended from the other end of the rope. The system is released from rest. 15 kg 12 kg a. Draw a free-body diagram for each object showing all applied forces on a relative scale. Next to each diagram show the direction of the acceleration of that object. b. Find the acceleration of each mass. c. What is the tension force in the rope?

A person exerts a force of 120 NN on a rope that pulls a sled across a very smooth horizontal surface. The rope is oriented 37⁰0 above the horizontal. The sled has a total mass of 50 kgkg. The sled starts at rest and moves for 10 mm. Select all the quantities that can be determined using the given information. A. Determine the acceleration of the sled. B. Determine the normal force exerted by the surface on the sled. C. Determine the time taken for the sled to move 10 m. D. Determine the speed of the sled after moving for 10 m. F. Check all that apply. acceleration of the sled normal force exerted by the surface on the sled mass of the person time taken for the sled to move 10 mm speed of the sled after moving 10 mm

Three boxes in contact slide side-by-side on a smooth, friction-less, horizontal floor. Their masses are 5.0-kg, 3.0-kg, and 2.0-kg, with the 3.0-kg box in the center. A force of 50 N pushes on the 5.0-kg box, which pushes against the other two boxes.   A. Draw the free-body diagrams for each of the boxes. B. What magnitude force does the 3.0-kg box exert on the 5.0-kg box? C. What magnitude force does the 3.0-kg box exert on the 2.0-kg box?

Please do A-C, Thank you!

A 10 N force is applied to a 4.0 kg block at rest on a table. The block experiences a frictional force. Draw a free-body diagram of the block.  What is the weight of the block?  What is the normal force on the block?  If the coefficient of kinetic friction is µk = 0.20, what is the kinetic frictional force on the block?  What is the net force on the block?  What is the acceleration of the block from the net force?  Just 1, 2, and 3 please!

Sledding A sled with a mass of 80.0 kg is pulled along flat, snow-covered ground. The static friction coefficient is 0.30, and the kinetic friction coefficient is 0.10. a. What does the sled weigh? b. What force will be needed to start the sled moving? c. What force is needed to keep the sled moving at a constant velocity? d. Once moving, what total force must be applied to the sled to accelerate it at 3.0 m/s??

while tom pushes a 40 kg box in horizontal direction along the classroom floor with a 100 N force, the box is moving in a straight line with constant speed of 0.5 m/s. Ignor air resistance when answering the questions below. a. Write down as much information as you can about the main horizontal forces exerted on the box ( names, directions and if enough information is given, numerical values). b. Write down as much information as you can about the main vertical forces exerted on the box (names, directions, and whenever possible, if enough information is given, numberical values). c. How far did the refrigerator move during those 3 seconds? Explain d. What was the refrigerator's acceleration during that time? Explain
