A couple of soccer balls of equal mass are kiched off the ground at the same speed but at different angles. Soccer ball A is kicked off at an angle slightly above the horizontak, whereas boll B is kicked slightly below the vertical. How do each of the following compare for ball Aand ball B? (a) The initial kinetic energy and (b) the change in gravitational potential energy from the ground to the highest point? If the energy in part (a) differs from part (b), explain why there is a differenne between the two energies.
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) If we know that a force of 5 N acts on an object while it moves 2 meters, can we calculate how much work was done with no other information? Explain.
Calculate the kinetic energy of a Boeing 767 that is 350,000lbm and travels at 400mph. Would I use the kinectic enrgy formula? Or the translation formula since it's in english units?
Suppose you lift a 25 kg box by a height of 1.0 m. How much work do you do in lifting the box? Instead of lifting the box straight up, suppose you push it up a 1.0 m high ramp that makes a 30 degree angle with the horizontal, as shown in (Figure 1). Being clever, you choose a ramp with no friction. How much force is required to push the box straight up the slope at a constant speed? How long is the ramp? Use your force and distance results to calculate the work you do in pushing the box up the ramp.
