A constant force is applied to a body that is already moving. The force is directed at an angle of 60 degrees to the direction of the body's velocity. What is most likely to happen is that

a. the body will stop moving. b. the body will move in the direction of the force. c. the body's velocity will increase in magnitude but not change direction. d. the body will gradually change direction more and more toward that of the force while speeding up. e. the body will first stop moving and then move in the direction of the force.
