- We know from the reading that it is possible to move the same object two different distances and still do the same amount of work. Let's consider an example in which Jane pushes a block of ice up an incline while Kip lift the same block of ice vertically to the top of the same incline. See the figure below. (look at picture) We will assume that there is no friction between the surface of the incline and the block of ice. Both of these situations will require the same amount of work and that the result of lifting the ice block to some height imparts potential energy to the ice. In this activity, we will make various calculation to help us better understand the relationship between work and potential energy and the idea of conservation of energy. For this activity we will assume that the mass of the ice block is 5.6 kg and the vertical height of the incline is 2 m. This is the vertical distance that Kip must lift the block of ice. We will assume that the acceleration due to gravity is 10…Calculate the work done (in J) by a 75.0 kg man who pushes a crate 4.30 m up along a ramp that makes an angle of 20.0° with the horizontal. (See the figure below.) He exerts a force of 540 N on the crate parallel to the ramp and moves at a constant speed. Be certain to include the work he does on the crate and on his body to get up the ramp.How much work is done by gravity when dead lifting a 100.0 kg barbell 64.11 cm from the floor to hip level [round your final answer to zero decimal places]?
- A 20m rope is hanging over the edge of a 50m building. Attached to the end is 2 kg bucket carrying 30kg of sand. There is a whole in the bucket that allows the sand to leak out at 0.5 kg/m. Disregarding the rope, how much work is done lifting the bucket to the top of the building? Show all work. Include units. Method of solving: fnint(), rounded to nearest whole number or Fundamental Theorem. Your choiceSuppose you carry a bag of groceries weighing 145 N from your car to your kitchen, a distance of 35 m, without raising or lowering the bag. What was the work done by the force you exert on the bag?Does the net work done on a particle depend on the choice of reference frame? yes no
