a nonzero net external force acts on object in Case B only (Second option)
A body can only accelerate if a net force acts on the body. If there is no net force acting, the body moves with constant velocity.

A 43.0 kg parachutist is moving straight downward with a speed of 3.70 m/s . If the parachutist comes to rest with constant acceleration over a distance of 0.775 m , what force does the ground exert on her? Express your answer to three significant figures and include the appropriate units. If the parachutist comes to rest over a shorter distance, is the force exerted by the ground greater than, less than, or the same as in part A? Explain.
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...

26. Can an object be moving at a constant speed, but still have acceleration? A. Yes, because the object is gaining speed at a constant rate. B. Yes, because the object is changing direction. C. No, if it's moving at a constant speed it is not accelerating. D. No, because the object will eventually slow down. 27.In the quantum theory of hydrogen, as an electron drops to lower EPE orbit, it emits a photon with missing energy equal to A....
