At the moment `t=0` the force `F=at` is applied to a small body of mass `m` resting on a smooth horizontal plane (a is constant).
The permanent direction of this force forms an angle `alpha` with the horizontal (figure). Find:
(a) the velocity of the body at the moment of its breaking off the plane,
(b) the distance traversed by the body up to this moment.

Answer

`[(mg^(2))/(2k),(costheta)/(sin^(2)theta),(m^(3)g^(3)costheta)/(6k^(2)sin^(3)theta)]`
