Why does velocity of an arrow change as it travels toward the target?

A velocity vector would include both a speed and direction.
Wind (air) resistance will affect the speed component, slowing down the arrow as time passes.
Gravity will pull it downward at a constant acceleration of 9.8 m/s2. This means that the downward component of the velocity will increase with time.
Wind, of course, could also throw the arrow off course.

A vehicle travels 2345m in 315 s toward the evening sun what is its velocity?
Lol, Dr moleski?
All objects change velocity as they move toward earth at a rate of 9.8 ms2 due to which factor of gravity?
acceleration
An airplane travels at 150 km per h toward the northeast what is the northern component of its velocity?
150 sin(45) = 150 ( sqrt(2) / 2 ) = 106.07 km/hr (rounded)
All objects change velocity as they move toward earth do to which factor of gravity?
i needed this question but chilish people and this jank cite wont give it to me
A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.

If two trains are 2000 miles apart on the some track one travels east at a velocity of 150 mph the other travels west at a velocity of 100 mph how long will it take for them to meet?
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.

How does one refer to the organ or structure toward which the effects of a hormone are directed?
Target organ can be defined as the organ or structure toward which the effects of a hormone are primarily directed. The target organ's activity levels demonstrate change in the course of biofeedback.

An earthworm crawled 35millimeters directly toward a rock at a constant velocity. It took the earthworm 2.5seconds to crawl that far. What was the earthworm's velocity?
14 millimeters per second Explanation; The velocity of an object is the distance it travels divided by the time it takes to travel that distance. In this case, the earthworm crawled 35 millimeters in 2.5 seconds, so its velocity was ( 350/2.5) = 14 millimeters per second.
