An object A moving horizontally with kinetic energy of 800 J experiences a constant opposing force of 100 N , while moving from a place x to a place y , where x y is 2 m . What is the energy of A at y ?

Question

Quantrex Academy · Accepted Answer

Correct answer: C. 600 J

Energy at y= total KE - work done from x to y=800-100 2=600 ~J
