- Problem 2 A rectangular tank that is 88 feet long, 33 feet wide, and 1515 feet tall is filled with a liquid that has a density of p pounds per cubic foot. If a spout is connected to the top of the tank, how much work will it take to pump all of the liquid out of the tank through the spout? Work= ______ How much work will it take to pump all of the liquid out of the tank through a spout that is T feet above the top of the tank? Work= _______ Answers should be in terms of p and T. Note: The answers are NOT 3332666700p and (2904p)((1515T)+(2295225/2))answer must be in proper format oe i will give down voteList the factors you need to measure to calculate the initial mechanical energy of the skater when he was at the top of the ramp and why you need them
- Which of the following would be a result of positive work being done on a moving car? * The car rounds a turn The car collides with an object The car slows down The car speeds upSpring Mass system A 52 Ib mass stretches a spring 4 inches. Find the work done by the force to stretch the spring 13 inches from its equilibrium position Note: Write the exact answer not the decimal approximation (for example write not 0.8). (i) Find the value of spring constant in Ib/ft Answer: (ii) Find the work done (in ft-lb) by the force to stretch the spring 13 inches from its equilibrium position Answer:The Super Sled travels with an initial kinetic energy of 3369 J horizontally and to the right along a frictionless flat surface, initially at a height of zero (initial gravitational potential energy = 0). The driver briefly engages the rocket over a distance (Ax) of 2.000 m, pushing the sled with a force of 400.0 N over that distance. The rocket is then turned off. The sled then goes up an inclined surface with a rough surface. The coefficient of kinetic friction on the incline is uk. At the top of the incline, the sled reaches a height h = 1.500 m above the ground where the surface becomes flat and frictionless again. The sled (including the rocket and driver) has a total mass of 87.00 kg. (Notes: assume that g = 9.810 m/s² , and that the mass of fuel used by the rocket is negligible. Do not use scientific notation). After &, rocket rocket Before propulsion propulsion starts ends rough inclined surface rocket frictionless engaged coefficient of kinetic friction = H surface h = 1.500 m…
