Which of the following is true as an object falls down in free fall? A. The acceleration is down and constant, which makes the object have an increase in speed/velocity as it falls.
B. The acceleration is increasing which makes the ball speed up as it falls.

the bal will not change its velocity.

we need to know the time interval during which the force acts. impulse of force = momentum change

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
