A body of mass m resting on a smooth horizontal plane starts moving under a constant force F. During its rectilinear motion, the angle theta between the direction of force and horizontal plane varies as 8 = kx , where k is a constant and x is the distance travelled by the body from the initial position. What is the velocity of the body?

1.	A body of mass m resting on a smooth horizontal plane starts moving under a constant force F. During its rectilinear motion, the angle theta between the direction of force and horizontal plane varies as 8 = kx , where k is a constant and x is the distance travelled by the body from the initial position. What is the velocity of the body?
Answer» `(2F)/m tan theta` `SQRT((2Fsin theta)/(mK)` `sqrt((Fcos theta)/(mk))` `sqrt((2Fcos theta)/(mk)` ANSWER :B
