Work Power Energy Exam2 and Problem Solutions 1. Applied force vs. position graph of an object is given below. Find the kinetic energy gained by the object at distance 12m. By using work and energy theorem we say that; area under the graph gives us work done by the force. ΔEK=W=area under the graph=(8+4)/2. 8-8(12-8) ΔEK=12. 4-8. 4=16 joule 2. Problems: Work, Energy, Power 1) A 10.0 kg mass sliding on ... Problems: Work, Energy, Power 1) A 10.0 kg mass sliding on a frictionless horizontal surface at 7.00 m/s hits a spring that is attached to a wall. The spring has a spring constant of 5000 N/m. a) Determine the maximum compression of the spring. At maximum compression, the box has a speed of zero. 10 Common Problems of Work and Power - Junior Physics physics.fisikastudycenter.com - Learning work and power in 10 common questions and the solutions.
