A mass of 1 kg is acted upon by a single force `F=(4hati+4hatj)N`. Under this force it is displaced from (0,0) to (1m,1m). If initially the speed of the particle was 2 `ms^(-1)`, its final speed should be

A body is acted upon by a force vec(F)=-hati+2hatj+3hatk . The work done by the force in displacing it from (0,0,0) to (0,0,4m) will be -

A constant force F=(hati+3hatj+4hatk)N acts on a particle and displace it from (-1m,2m,1m)to(2m,-3m,1m).

Force acting on a particle moving in the x-y plane is vecF=(y^2hati+xhatj)N , x and y are in metre. As shown in figure, the particle moves from the origin O to point A (6m, 6m) . The figure shows three paths, OLA, OMA, and OA for the motion of the particle from O to A. Now consider another situation. A force vecF=(4hati+3hatj)N acts on a particle of mass 2kg . The particle under the action of this force moves from the origin to a point A (4m, -8m) . Initial speed of the particle, i.e., its speed at the origin is 2sqrt6ms^-1 . Figure shows three paths for the motion of the particle from O to A. Speed of the particle at A will be nearly
