A 25 kg air compressor is dragged up a rough incline from T1 T2 = (8.3î + 4.45) m, where the y-axis is = (1.3î + 1.33) m to %3D vertical.

How much work can a 1950 Watt motor do in 15 min? Express your answer in Joules.

A spider walks on a path that is at 25 ∘. Calculate the power output of a 0.42g spider as it walks up a windowpane at v =2.5 cm/s. Answer in Watts

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…

A person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time: (a) How many people would it take to run a 4.00 kW electric clothes dryer? people (b) How many people would it take to replace a large electric power plant that generates 900 MW? people Additional Materials O Reading
