10. A 50-kg box is 10 meters above the floor. This box is lifted 20 meters to point B. It is then lowered 25 meters to point C. a. What is the change in potential energy of the box between points A and C? b. What power is required to move the box from point A to point in 20 seconds? Give answer in both Watts and horsepower.
The floors in a building are 3 meters apart. An elevator requires 1 meter to speed up and 1 meter to slow down again. For the following boring story, sketch carefulgraphs of position, velocity and acceleration vs. time An elevator goes from the second floor to the fourth floor and stops to take on passengers. It then goes to the tenth floor to drop them off, and returns to the lobby on the first floor.
An engineer builds a 1 square meter dish to collect light from a distant 100 [Watt] incandescent light bulb. Assume that the entire 100 Watts of electrical power that the bulb consumes is radiated as light. If the bulb radiates uniformly in all directions and is 1 kilometer away from the engineer's collection dish, approximately how much energy will the dish will collect every second? Assume no other light is present to contaminate the signal and assume the dish is...
Conservation of Energy/Power Problem: The Sears tower has elevators that weigh 1000kg each. If the elevator is lifted 400m to one of the upper floors in a total of 15s. (You will need to use the kinematic equations for some parts of this problem) Part 1. How much Power must the engine doing the lifting be rated for? Give your answer to the nearest kilo-Watt (1 kW = 1000 W). kW Part 2. What is the Potential Energy of the...
Calculate the electric potential V at a distance r from an infinite line charge, density rho_t Coulombs per meter. From the potential calculate the electric field and show that the field is identical to what we derived in class You will find that difficulties will arise when integrating from -infinity to infinity to find V. Try this: calculate the potential and the field for a segment of line charge 2L meters long (i.e., integrate from -L to +L). Once the...
