From Newton's second law of motion, force is the product of mass and acceleration. In turn, acceleration is obtained by dividing the velocity by time. That is,
                                          F = ma = mv/t
We can say that force is directly proportional to velocity such that an increase in force will increase the velocity. Thus, the final speed of 15 Newtons will be the greatest among the forces. 

B) The final acceleration will triple between the first and third trial.
