A stone that falls from a ledge and takes 8 second to hit the ground travels a distance of 313.6 meters. You can find this answer by substituting 8 seconds for time in the physics formula d = 1/2 x acceleration x (t squared), where d = distance, acceleration is given as a =9.8 meters/second squared, and t squared is time in seconds.
There is 1 million seconds in a Mega-second.
It's a deceleration of 2.93 meters per second squared
There is no such unit as "macro second".
There are 10-15 seconds in a femtosecond.
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.
The answer is B - 3 meters per second squared
-6.667 miles per second squared
To convert 4.4 miles per hour per second to meters per second squared, first convert 4.4 miles to meters (1 mile = 1609.34 meters) and 1 hour to seconds (1 hour = 3600 seconds). Then divide the speed in meters per second by the time in seconds squared to get the acceleration in meters per second squared.
10 feet per second squared
3 metres per second squared
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.
Acceleration measures the rate of change of velocity over time. The squared seconds unit is used because acceleration is the change in velocity per unit time, so it is expressed as distance per time squared. This allows us to quantify how quickly the velocity of an object is changing over time.
-66.667 miles per second squared
A gain of 2 miles per second squared
Seconds times seconds -- for example, the acceleration of a falling body in the earth's gravitational field is equal to 9.8 metres per second squared, so if a body has been falling for 5 seconds, the equation reads 9.8M x 5 x 5
Acceleration is measured in m/s2 (metres per second squared)
