Newton's second law: Rudolph the red nosed reindeer is pulling a 25 kg sled across the...
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...
. You are using a rope to pull a sled at a constant velocity across level snow, with coefficient of kinetic friction 0.050 between sled and the snow. The sled is loaded with physics books, giving a total mass of 48 kg. (a) With what force should you pull with the rope horizontal? (b) Repeat for the rope at 30 ̊above horizontal.
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 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...
Problem 4 A child is dragging a 2kg sled through a flat patch of snow (coefficient of kinetic friction: 0.1) with a constant force, by pulling on a rope at an angle of 25° to the horizontal. The sled is moving at a constant speed. (a) Draw a free body diagram for the sled as it is being pulled. (b) Find the magnitude of all the forces acting on the sled. (c) If the child were to suddenly release the...
1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...
Daisy is pulling a 15.8 kg sled to the right over a rough surface with a single horizontal rope. The tension in the rope is 100.2 N and the force of friction between the surface and the sled is 52.3 N . What is the acceleration of the sled? Express your answer in meters per second squared and round to one decimal place.
Daisy is pulling a 20 kg sled to the right over a rough surface with a single horizontal rope. The tension in the rope is 100.8 N and the force of friction between the surface and the sled is 65.7 N . What is the acceleration of the sled? Express your answer in meters per second squared and round to one decimal place.
A 5.0 kg penguin sits on top of a 12 kg sled, as in the figure. A horizontal force of 45 N is applied to the sled, but the penguin keeps himself stationary by holding onto a string attached to the wall. The coefficient of kinetic friction between the penguin and the sled is 0.18, and the coefficient of kinetic friction between the sled and the snow is 0.14. (4 marks) 45N Draw force diagrams for the penguin and the...
By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...
