What is the centripetal acceleration of an object being swung on a string with a radius of 5 meters at a velocity of 4 meters a second?
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
How do you convert radians per second to meters per minute?
First you must know the radius of whatever is moving in a circle. The relationship is: linear speed (meters/second) = angular speed (radians/second) x radius. The result, as hinted in the units, will be in meters/second. Converting that to meters/minute is easy; you just multiply by 60.
How much does its speed change after 5 minutes with an acceleration of 470 meters per second?
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.

What is the centripetal acceleration of an object being swung on a string with a radius of 3 meters at a velocity of 4 meters per second?
Use the formula for centripetal acceleration: velocity squared / radius.
Is earth accelerating right now?
Yes. When it moves around the Sun, there is circular acceleration, that can be calculated via the formula a = v2 / r. Velocity should be converted to meters / second, radius (of the orbit) to meters - in this case, the result is in meters per second squared.Yes.

How are radius and speed related?
Usually they aren't. But you may want to give more details about the specific situation you were thinking about. In the case of rotational movement, the linear speed (in meters/second) is equal to the rotational speed (in radians/second) times the radius (in meters).
If you travel 48 meters radius in 7 seconds what would the valocity be?
Velocity = distance divided by time measured in meters/second, so it would be 48/7 which is 6.85 meters per second
How do you convert radians per second to meters per second?
the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
What is acceleration and its si unit?
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

Why are the units for acceleration meters per second?
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
How do you convert rpm to meter per second?
To convert revolutions per minute (rpm) to meters per second, you need to consider the circumference of the rotating object. First, calculate the distance traveled in one revolution by multiplying the circumference of the object by the number of revolutions per minute. Then, convert the result to meters per second by dividing by 60 (to convert minutes to seconds). The formula is: speed (m/s) = (rpm * 2πr) / 60, where r is the radius of the rotating object.
What is a car's acceleration if it increases its speed from 5 meters per second to 20 meters per second in 3 seconds?
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
