What is the acceleration of a rain drop that falls at a constant velocity?

This is not a simple question and not enough information is provided to answer it. Among other things it depends upon the time it takes to reach terminal velocity and the terminal velocity depends on the various drag forces operating which in turn will depend on other variables such as initial height, wind speed, temperature, humidity, etc. You could calculate the velocity of any object falling in a vacuum if the acceleration due to gravitational force remains constant throughout the fall. v=v0+at where vo=initial velocity (probably zero if the object is initially at rest), a is the acceleration due to gravity (9.8m/s2) at or near the surface of the earth, and t is the time of fall.

What is acceleration of a rain drop that falls at a constant velocity?
If the velocity is constant then there is no acceleration. The acceleration is zero.
What is the velocity of a ball dropped on the surface of Mars if the acceleration of gravity is 3.7 meters per second squared?
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
What does uniformly accelerated linear motion mean?
If a body is uniformly accelerated, then it's velocity is changing by equal amounts in equal times. Suppose you drop a lead ball from a high tower. At the moment you drop it, its velocity is zero and it accelerates to 10 metres per second in the first second. In the fifth second for example it accelerates from 40 m/s to 50 m/s. The acceleation is ten more metres per second over each second. That is a constant acceleration. A steadily increasing velocity. In real life, the falling ball would not have constant acceleration because the faster it falls, the greater is the air resistance which tries to slow it down. If the ball falls from a high enough tower, its speed will become almost constant because the air resistance force upward will be close to the weight force downward and the acceleration will disappear. The ball reaches "terminal velocity". Linear motion is motion in a straight line, no sideways disturbances.
If a train is stopped suddenly then it's acceleration will be zero or it's velocity will be zero?
As it slows it's acceleration will be negative, deceleration is negative acceleration. During the slow down the velocity will drop. Once at rest both acceleration and velocity will be zero.
Does rain drop fall with constant velocity?
No it does not, as a raindrop falls to earth it will gradually slow due to the changing terminal velocity. As a raindrop falls, water will evaporate from it causing the mass to decrease faster than the size and surface area. this will leave the raindrop with a higher surface area to mass ratio. Since air resistance is related to surface area and mass, the smaller raindrop will have more air resistance for its mass and will fall slower.
What happpens to velocity as a drop distance increases relate this to the concept of terminal velocity?
A falling body initially falls at a rate of -9.8m/s2, the acceleration due to gravity. Because of the drag force of the air, which is an upward force that opposes the force of gravity, the body's acceleration will decrease as it continues falling. When the drag force equals the weight of the falling body, there will be no further acceleration, and the body will have reached terminal velocity.
What is the terminal velocity of a falling object on earth?
An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.
Can a rapidly moving body have the same acceleration as a slowly moving one?
An object's inertia is its resistance to changes in its motion and mass is the quantitative measure of inertia. Strictly speaking the object's inertia will become larger the faster it goes. But at typical speeds it is unmeasurable or barely measurable . Only when the object's speed is near the speed of light is there a large change in its inertia.
An object will have constant acceleration if?
well, something has to be pushed by a constantly growing force. Constant acceleration would occur for example if you drop something in a vacuum. Dropping something in normal circumstances is a nearly constant acceleration too.
Will leaving a force constant and doubling the mass of an object cause the acceleration to double?
Just the opposite. It will cause the acceleration to drop by 50%.
Can an object be moving when its acceleration is zero?
Acceleration, which is the change of velocity over the change in time, will equal zero when there is no change in velocity. This can occur when an object is stationary or when an object is traveling at a constant velocity.
Can an object reverse its direction while maintaining a constant acceleration?
One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.
