At the instant t=0 , a force F=kt (k is a constant) acts on a small body of mass m resting on a smooth horizontal surface. The time, when the body leaves the surface is

At the instant t=0 , a force F=kt (k is a constant) acts on a small body of mass m resting on a smooth horizontal surface. The time, when the body leaves the surface is

At t=0 , a force F=at^(2) is applied to a small body of mass m at an angle alpha resting on a smooth horizontal plane

At the moment t=0 force F=kt is applied to a small body of mass m resting on a smooth horizontal plane (k is a constant) The direction of this force always forms an angle theta with the horizontal as shown. Find the time t at which moment, the body breaks off the plane:

At the moment t = 0, the foce F = kt is applied to a small body of mass 'm' resting on a smooth horizontal plane, (K is a positive constant ) . The direction of the force forms an angle theta with the horizontal always as shown which of the option (s) is /are correct ?
