Toon train is traveling at the speed of 10 m s at the top of a hill Five seconds later it reaches the bottom of the hill and is moving at 30 m s what is the rate of acceleration of toon train?

Rate of acceleration = Change in speed/time
= (30 m/s - 10 m/s) / 5 s
= (20 m/s )5 s = 20/5 ms-2 = 4 ms-2

What is the final speed of the marble at the bottom of the straight ramp and loop ramp?
A marble traveling at 3.0m/s starts to acceleration at 4.5m/s over a distance of 25m. what is the final speed of the marble?
A stone falls from a ledge it takes 16sec?
If a stone falls from a ledge and takes 16 seconds to hit bottom, then the bottom is 1413 meters away. This assumes acceleration due to gravity of 9.81 meters per second squared, an initial velocity of zero, and no friction due to air resistance. Air resistance will decrease the distance.x = 1/2 at2 + v0t + x0
On sound recorder how to you record your voice for longer than 60 seconds?
when it has reached 60 seconds, click on the record bottom at the end a click it.
It takes 6 seconds for a stone to fall to the bottom of a well what is the height?
We can't tell the height; but the distance between the top and the bottom is 578.7 feet. (rounded)
Reading the volume of liquid inside the graduated cylinder?
Always read from the bottom of the meniscus (where the liquid reaches up the side of the container).
If a rock falls from a cliff for 9 seconds how fast is it going when it reaches the bottom?
The speed of the rock when it reaches the bottom of the cliff can be calculated using the formula for free fall: speed = acceleration due to gravity x time. Given the acceleration due to gravity is approximately 9.81 m/s^2 and the time is 9 seconds, the speed of the rock when it reaches the bottom will be approximately 88.29 m/s.
What is the final speed of the marble at the bottom of the straight ramp and loop ramp?
A marble traveling at 3.0m/s starts to acceleration at 4.5m/s over a distance of 25m. what is the final speed of the marble?
For simple harmonic oscillator where is the greatest acceleration?
The acceleration is greatest at the top and bottom of the motion.
If it takes 6 seconds for a stone to fall to the bottom of the mine how deep is the mine?
The depth of the mine can be calculated using the formula: distance = 1/2 * acceleration due to gravity * time squared. Given the time is 6 seconds and the acceleration due to gravity is about 9.8 m/s^2, the depth of the mine would be approximately 176.4 meters.
A student drops a stone into a mine shaft It takes 3 seconds for the stone to hit the bottom of the shaft How deep is the mine?
The depth of the mine can be calculated using the formula: distance = 0.5 * acceleration due to gravity * time^2. Given that the time taken for the stone to hit the bottom is 3 seconds, we can substitute this into the formula along with the acceleration due to gravity (9.8 m/s^2) to calculate the depth of the mine. The depth of the mine would be approximately 44.1 meters.
What happens to the velocity of a ball that is rolling down a hill?
The velocity of a ball rolling down a hill will increase due to the acceleration caused by the pull of gravity. As the ball gains speed, its velocity will continue to increase until it reaches the bottom of the hill.
What is the duration of The Dollar Bottom?
The duration of The Dollar Bottom is 1980.0 seconds.
A rock is dropped from a height of 30 m and is in free fall What is the velocity of the rock as it reaches the ground 2.5 seconds later?
The velocity of the rock when it reaches the ground after falling for 2.5 seconds can be found using the kinematic equation: v = gt where: v = final velocity (m/s) g = acceleration due to gravity (9.81 m/s^2) t = time (2.5 seconds) Plugging in the values: v = 9.81 m/s^2 * 2.5 s = 24.525 m/s Therefore, the velocity of the rock as it reaches the ground is approximately 24.525 m/s.
What is the duration of WWE Bottom Line?
The duration of WWE Bottom Line is 2700.0 seconds.

Answer this question… How fast will a sled be moving when it reaches the bottom of a hill?
Is it true that if everybody in china will jump at the same time there will be having an earthquake?
That's no more true than it is to say that if everybody in an elevator will jump up when the elevator reaches the bottom, there will be no people on the floor of the elevator when it reaches bottom.
