A body of mass `8kg` is moved by a force `F = (3x)N`, where x is the disatance covered Initial position is `x =2m` and final position is `x =10m` If initially the body is at rest find the final speed .

A body of mass 8kg is moved by a force F =3x N, where x is the distance covered . Initial position is x= 2m and final position is x = 10m . If initialy the body is at rest , find the final speed .

A body of mass 8kg is moved by a force F =3x N, where x is the distance covered . Initial position is x= 2m and final position is x = 10m . If initialy the body is at rest , find the final speed .

An object of mass 8 kg starts to move from rest under the action of a variable force F=3xN where x is the distance (in m) covered by the object. If initially, the position of the object is x = 2 m, then find its speed ("in m s"^(-1)) when it crosses x = 10 m.

An object of mass 8 kg starts to move from rest under the action of a variable force F=3xN where x is the distance (in m) covered by the object. If initially, the position of the object is x = 2 m, then find its speed ("in m s"^(-1)) when it crosses x = 10 m.

A particle of mass m is subject to a force (F) .Find the time dependent position x(t) of the particle for the following two cases : (a) F(x)=kx, with k>0, the initial position is x_(0) , and the initial speed is zero. (b) F(v)=-bv^(2) and the initial position is zero,and the initial speed is v_(0) .

A body of mass 10 kg is moving with a velocity of 20 m s^(-1) . If the mass of the body is doubled and its velocity is halved, find : (i) the initial kinetic energy, and (ii) the final kinetic energy

A nody of mass 5 kg is acted upon by a variable force. The force varies with the distance covered by the body. Then find speed of the body when the body has covered 25 m (Assume that the body starts from rest).
