Ahot-air balloonist, rising vertically with a constant velocity of magnitude v = 5.00 m/s , releases a sandbag at an instant when the balloon is a height h = 40.0 m above the ground (figure 1). after it is released, the sandbag is in free fall. for the questions that follow, take the origin of the coordinate system used for measuring displacements to be at the ground, and upward displacements to be positive.
a-) compute the position of the sandbag at a time 0.335 s after its release.
b-)compute the velocity of the sandbag at a time 0.335 s after its release.
c-) compute the position of the sandbag at a time 1.50 s after its release.
d-)compute the velocity of the sandbag at a time 1.50 s after its release.

No because scientist are still changing there mines today so they are not correct to this day

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
