Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As...
(20 pts) A sled loaded with firewood is pulled by a tractor. The tractor exerts a constant force with magnitude 2000 N in the horizontal direction. The total weight of the sled and the firewood is 3000 N, and the coefficient of kinetic friction between the sled and the road is 0.30. If the sled travels a distance of 5.0 m, (a) show the free-body diagram, (b) calculate the work done on the sled by the tractor, (c) calculate the...
A farmer attaches a tractor to a sled filled with firewood with chains at an agle of 33.5 0 as shown. If the tractor exerts a constant force of 5125 N above the horizontal and pulls it a distance of 20.0 m, find the work (J) done on the sled, neglecting friction. NEA 0
An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. The coefficient of kinetic friction between the sled and the ground is 0.200. (a) The Eskimo pulls the sled 6.00 m, exerting a force of 1.15 102 N at an angle of θ = 0°. Find the work done on the...
The eskimo pulls the sled 4.90 m, exterting a force of 1.10 x 10^2 N at an angle of 0 degrees. Find the work done on the sled by friction, and the net work.
Since 1967, Tractor Pull competitors from around the country have met at the Wood County Fairgrounds in Bowling Green, Ohio, for the National Tractor Pulling Championship (www.pulltown.com). The tractor or truck attempts to pull a heavy weight (called the “sled”) as far as possible, up to the length of the track (320 feet). You are part of the first ever Penn State Tractor Pull team, which will be competing in the National Tractor Pulling Championship. As a physics student, 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.
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...
Could you please explain? Thank you! kg15kg 20° B2007 A child pulls a 15 kg sled containing a 5.0 kg dog along a straight path on a horizontal surface. He exerts a force of 55 N on the sled at an angle of 20° above the horizontal, as shown in the figure above. Assume a constant friction force of 40N. (a) On the dot below that represents the sled-dog system, draw and label a free-body diagram for the system as...
A person pulls a block across a rough horizontal surface at a constant speed by applying a force F at a slight angle as shown. A free-body force diagram is drawn for the block. The arrows in the diagram correctly indicate the directions, but not necessarily the magnitudes of the various forces on the block A student states that F fk and Fv W (here W stands for weight, which we call Fc) since the velocity is constant and thus...
B200761. (15 points) A chilt pulls a 25 kg sled containing a 3.0 kg dog along a straight path on a horizontal surface. He exerts a force of SN on the sled at an angle of 30° above the horizontal, as shown in the figure above. The coefficient of friction between the sled and the surface is 0.2 (a) On the dot below that represents the sled-dog system, draw and label a free-body diagram for the system as it is...
