- In the above problem energy flows fromYou observe a car of mass 500 kg, moving at speed 5 m/s, collide with a 100 kg trailer that was at rest before the collision. When does the trailer do work on the car? Choose all that are correct. before the collision during the collision after the collision none of theseHow much work was done if an objects kinetic energy changes from 35 J to 15 J? A) -20 J B) 20 J C) 50 J D) 525 J
- Please answer question and just send me the paper solutions asap dont type the answer please question 6abc please give me the right solutions and answers please and label the given and draw a diagram and show the work please help me faster asap and don't give wrong answerThe 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…Needed to be solved this question correctly in 20 minutes and get the thumbs up please show me neat and clean work for it by hand solution needed only
