On a body of mass m that is in a smooth horizontal plane began to act at
the time t = 0 a force that depends on time according to the law F = ct,
where c is a constant. The direction of this force constantly forms an
angle a with the horizontal direction, calculate:
a) The velocity of the body at the moment of separation from the plane
b) The body's journey at this moment.
