- What are three different units used for work? You may include either the unit or itsKatrina pushes off a flat sidewalk on her new skateboard. (friction is present*)two people each exert a force of 300N pulling a car by seperate ropes in the east direction. the first person pulls at an angle of 20.0 degrees N of E and the second person pulls at angle of 20.0 degrees S of E calculate the work done on the car by each worker if the car moves 0.50m/s for 5.6s
- Communication 1. Determine whether or not the path travelled has an effect on the work being performed if the starting point and ending point remain the same. Consider cases when there is only one constant force acting on an object and other times when the forces acting on the object depend on the path. Give an example of each.A force, varying with distance as shown in the graph below, acts on a 5.5 kg object. When is most work done, in the first 4 meters or between 4 and 6 meters? Explain your response. 4.0 3.0 2.0 1.0 2.0 4.0 6.0 8.0 Find the work done by the force in moving the object from 0 m to 6.0 m. Explain your calculation and give units. Figure 9-15 C. Assuming that there is no friction or air resistance what is the total change in the object's energy? Explain your answer. b. FORCE (N)A cart for hauling ore out of a gold mine has a mass of 443 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.01° incline. Track -.Rope A Track incline Horizontal ground Find the work Wa that the donkey performs on the cart during this process. Find the work Wg that the force of gravity performs on the cart during this process. Calculate the work Wf done on the cart by friction during this process. 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 389 N force for a distance of 157 m by means of a rope that is parallel to the slope but makes an angle of 13.5° with the track. Model the rolling resistance of the cart as though it were sliding on the track with a coefficient of friction of 0.0171. Use g = 9.81 m/s², and note that angle A in the image is the angle of the incline while angle B is the angle the rope makes with the track. Wa = J J W% = W₤ = J
