From a dead stop if a train begins accelerating at a constant 3 times gravity how long must the track be till the train reaches 1000 meters per second?

The train will reach 1000 m/s after 34.0 seconds, it will have travelled 17006.8 metres by that time.

Which term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
terminal
Which term refers to the speed at a falling object stops accelerating and begins to fall at a constant rate?
Terminal Velocity
What term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
The speed is called "terminal velocity".
What is the driving force behind glacial movement?
Once the depth of snow and ice reaches more than 30 to 40 meters, gravity begins to pull the glacier down hill.Also as the glacier melts due to pressure if creates melt water which acts as a lubricant.
Is 0 velocity and 0 acceleration correctly describes the velocity and acceleration of the rock at the exact top of its path?
No. Any object that was shot by gun, flung by slingshot, or thrown by hand, begins accelerating downward at the acceleration of gravity as soon as it leaves the propulsion system. Zero velocity is true at the top, but acceleration is constant throughout the trajectory ... 9.8 m/s downward.

Is a bullet going through the barrel of a rifle accelerating?
Yes. It starts at zero- and when fired, begins to accelerate until it reaches it's greatest speed- usually before getting to the muzzle of the gun.

Can an object be accelerating when it speed is zero?
Yes. There can be an instant during a period of acceleration when speed is zero. We can think of two examples right away: 1). Drop an object from your hand. As soon as you release it, downward acceleration begins immediately, but speed is zero. 2). Toss an object (like a baseball or a stone) straight up. Downward acceleration due to gravity begins immediately. At first, its effect is to reduce the upward speed. As soon as the upward speed is all gone, downward speed begins. Acceleration is constant throughout, but at the instant when upward speed becomes downward speed, the speed is zero.
Is there a word from Space that begins with z?
Zero gravity is a space word. It begins with the letter z.
Can an object have zero velocity and non-zero acceleration?
Yes, an object can have have zero velocity and non-zero acceleration. This happens when an object is at rest and when a force is applied on it such as gravity. But this isn't always true. A good example of another situation is when you throw an object vertically up into the air. Such an object will be acted upon by the constant acceleration of gravity. Due to this acceleration, it will slow down, then it will reverse direction, and finally it will fall back to the ground. At the exact point at the top of its path before falling back down, the object will have zero velocity. Yet it will still be accelerating towards the ground the whole time. The object is being accelerated by the force of gravity throughout its entire journey.
