What else can I help you with?
A ball is thrown horizontally from a cliff at a speed of 8 meters per second. What is its speed one second later?
After a second, the ball will still have a horizontal velocity of 8 meters per second. It will also have a vertical velocity of 9.8 meters per second (Earth's acceleration is about 9.8 meters per square second). The combined speed (using the Law of Pythagoras) is about 12.65 meters per second.
How long does it take to go around the earth at light speed?
The circumference of the Earth is ~24902 miles or 40,076,000 meters. This speed of light is 299,792,458 m/s. So it takes 0.134 seconds to go around the earth once.
What is the average walking speed of a person in meters per second?
The average walking speed of a person is around 1.4 to 1.6 meters per second. This speed can vary based on factors like age, fitness level, and terrain.
What is the speed of light in meters per second?
The speed of light in a vacuum is approximately 299,792,458 meters per second.
What is the speed of the electron in its orbit?
The speed of an electron in its orbit around an atom is approximately 2.18 million meters per second.
What is da speed of light?
About 300,000,000 meters per second - enough to go around the Earth 7.5 times in a single second.
What is the speed of light on earth through air?
299,792,458 meters/second

What is the speed of sound on the moon?
The speed of sound on the moon is about 1,640 meters per second, compared to around 343 meters per second on Earth. This difference is due to the moon's lack of atmosphere, which affects the propagation of sound waves.
How long does it take to go around the earth at light speed?

How fast does the speed of sound go from mars to earth?
The speed of sound varies depending on the medium it is traveling through. In Earth's atmosphere, the speed of sound is about 343 meters per second. On Mars, where the atmosphere is much thinner, the speed of sound would be slower than on Earth. Therefore, the speed of sound from Mars to Earth would be slower than 343 meters per second.
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes What was the jogger's average speed in meters per second?
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes his average speed (pace) is 1.0285 meters per second.
How do you convert speed in meters per second?
so you calculate for one second howmuch meters do you pass and the number that you had is your speed on meters per second
What is the SI unit for tangential speed?
The SI unit for tangential speed is meters per second (m/s).
What is 9.8 meters per second used for?
(.8 m/s is used for the speed after one second of gravitational acceleration on earth.
What speed does an object on earth free fall?
If their is no air resistance, it will go faster and faster, at a rate of 9.8 (meters / second) / second.
What happens to a spacecraft that is launched at a speed less than 8000 meters per second?
If a spacecraft is launched at a speed less than 8000 meters per second, it may not have enough velocity to escape Earth's gravitational pull and enter orbit around the planet. Instead, it may re-enter the Earth's atmosphere and burn up due to friction with the air.
