At the moment t = 0 , the force F = kt is applied to a small body of mass 'm' resting on a smoth horizontal plane. (K is a positive constant ). The direction of the force an angle `theta` with the horizontal always as shown

The distance travelled x by the body along horizontal before it leaves contact with the horizontal at `t =t_0` can be expressed in relation with time 't' as

Options

A. `x prop t^2`
B. `x prop t^3`
C. `x prop t^(3//2)`
D. `x prop t^4`

Answer

B
