The linear momentum P of a body varies with time is given by the equation P=x+yt^2 where x and you are constant . the net force acting on the body for one directional motion is proportional to : a)t^2 b)A constant c)td)1/t sorry it's of chemistry
hello friendsA body of mass 2 kg moving with velocity 4 m/s horizontally stops after 2s . if the body is to be kept in motion at the same surface with 4m/s,force needed is:a)1Nb)2Nc)4Nd)18N
