Answer #1

From Newton's second law, Force equals mass times acceleration, i.e F = m*a , So if the force F is constant implies m*a is constant , this inturn implies acceleration is inversely proportional to mass. So if the mass of the object is decreased then the acceleration of the object is increased. So the answer is A) the magnitude of the acceleration would increase.

  • If a single constant force acts on an object that moves on a straight line

    If a single constant force acts on an object that moves on a straight line, the object's velocity is a linear function of time. The equation v=vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi-vx, where k is a...
