Hi there!! My question is bolded below :) It is a multiple choice question, so I have also listed every possible answer. A person with a mass of 42kg starts from rest at position A, as shown, and then slides down to positions B, C, and D. Calculate the gravitational potential energy of the person at A. 412 J 672 J 4.2 kJ 6.6 kJ Thanks!
Wile E Coyote (below) has a mass of 12.5 kg and compresses a spring with spring constant 150 N/m by 0.90 m before he stops touching the floor and hence is shot out by the spring. a) What is the potential energy stored in the spring at maximum compression? b) What is the speed of the Wile E Coyote right after the spring returns to its uncompressed position? c) What is the work done by the spring on Wile E Coyote?
A 62.6 kg runner has a speed of 5.30 m/s at one instant during a long-distance event. HINT What is the runner's kinetic energy at this instant (in J)? J (b) How much net work (in J) is required to triple his speed? J
You push a box up a ramp (friction between the box and the ramp is not negligible). Call the initial state when you begin to push the box. Call the final state after you have pushed the box up the ramp a distance of 0.5 m and it is moving with a speed of 2 m/s For which of the following systems does the energy remain constant?A. System: box + ramp + Earth + youB. System: boxC. System: box + ramp + EarthD. System: youE. System: box + rampF. None of the above. Two cars are driving down the road. They notice that they are going to crash, so both drivers slam on the brakes. The cars skid, but still collide. The cars stick together and eventually slide to a stop. Call the initial state just before the drivers apply the brakes and the final state just after the collision had occurred. Treat this situation as realistically as possible. For which of the following systems does the energy remain constant?A. System: both carsB. System: both cars + the groundC. System: the second carD. System:…
