Imagine yourself pulling your luggage on the snow with a rope that makes an angle of...
Shortly after the start of a dogsled race, you find yourself pulling your supplies across the snow (those $#@*&%^*& sled dogs are in BIG trouble). You apply a force of 300 N to a rope that is attached to the front box at an angle of 20 degrees above the horizontal. Mass of the front box M=40Kg, mass of the black box m=30kg, and there is no friction between the boxes and the snow. A)Draw a free-body diagram of each...
You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...
You are pulling a box of toys along the floor with a rope that makes an angle of 30° above the floor. If the tension in the rope is 50 N, what is the work done by the tension when the box of toys moves through a displacement of 3 m? Select one: a. 150 J b. 75 J c. 20 J d. 130J e. 50 J
A sled is being pulled across rough snow by a rope at an angle of 20° to the horizontal. The sled has a mass of 31 kg and the passenger has a mass of 22 kg. The sled is moving at a steady 0.63 m/s. The force on the rope is 65 N. A. Draw a free body diagram for the sled and passenger as one thing. B. What is the normal force on the sled? C. What is the...
A boy pulls a 5.0-kg sled with a rope that makes a 60.0° angle with respect to the horizontal surface of a frozen pond. The boy pulls on the rope with a force of 10.0 N, and the sled moves with constant velocity. What is the coefficient of friction between the sled and the ice? A) 0.09 B) 0.10 C) 0.18 D) 0.06 E) 0.24 The answer is C 0.18, I don't undersatnd why.
) child is pulled along the flat ground on snow on a sled by his father. The child and sled together have a mass of 33 kg. The father pulls the sled by a rope 40 degree angle above the horizontal. If the coefficient of friction between the snow and the sled is. 16, determine the force the father must pull with to maintain constant velocity. (you mus which is angled upward at a nd th e Normal Force and...
You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...
An object with mass m is dragged along a horizontal plane by a force acting along a rope attached to the object as shown below mass horizontal plane If the rope makes an angle θ with the plane, then the magnitude of the force required to overcome friction is where g is the acceleration due to gravity and μ is a positive constant called the coefficient of riction, and we assume θ [0, π/2) Use the second derivative t tan...
You have a crate full of books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to start moving? (b) Once...
Question 22 of 22 > Track ... Rope . A cart for hauling ore out of a gold mine has a mass of 445 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.55° incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 444 N force for a distance of 201 m by means...
