Suppose we know a body's mass, its initial velocity, and everything about the forces which act on it, with respect to an inertial frame. This is the only information we have about the body. Can we predict where it will be at some later time?

Answers

answer 1 Yes, all we have to do is solve the differential equation from Newton's first law.

answer 2 Yes, all we have to do is solve the differential equation from Newton's second law.

answer 3 Yes, all we have to do is use conservation of momentum.

answer 4 Yes, all we have to do is use conservation of energy.

none of the above
