49. A variable force given by the two dimensional vector vector F= 3( x to the power 2 i CAP) + 4 j cap acts on a particle. The force is in Newton and x is in metre what is the change in the kinetic energy of the particles as it moves from the point with coordinates (2,3) to( 3,0)the coordinates are in metre. |
