Question 1
A constant force F is applied to a body of mass m that initially is headed east at velocity v0 until its velocity becomes −v0. The total time of travel is 2t. The total distance the body travels in that time is

Question 2
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
◦
the body will stop moving.
◦
the body will move in the direction of the force.
◦
the body's velocity will increase in magnitude but not change direction.
◦
the body will gradually change direction more and more toward that of the force while speeding up.
◦
the body will first stop moving and then move in the direction of the force.
