What is a cars acceleration if it increases its speed from 5 m s to 20 m s in 3 s?
The answer will be 5 m/sec/sec 300m/sec - 200m/sec divided by 20 seconds will get you 100m/sec divided by 20 seconds, which then equals 5
In a test run a certain car accelerates uniformly from zero to 24 meters per second in 2.95s what is the magnitude of the cars acceleration?
The car's uniform acceleration is (change in speed) divided by (change in time) = (24 m/s) / (2.95 s) = 8.1356 meters/sec2. Call this number ' A ' for acceleration. Change in speed = ( A ) times (time) Time = (change in speed) / A = (20 - 10) / A = 10/A = 0.81356 seconds (rounded)
A car accelerates to pass a truck going from 20 ms to 29 ms in 3 seconds what was the acceleration.?
Acceleration = (change in speed) divided by (time for the change) = (9/3) = 3 m/s2
What is the distance if the acceleration is 0.5 meters per sec square at 20 seconds?
If you assume that the initial speed is zero, you can calculate the distance using the formula:distance = 1/2 x acceleration x time squared
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
What is a cars acceleration if it increases its speed from 5 to 20 in 3 seconds?
Acceleration = change in speed/time = (20-5)/3 = 15/3 = 5 units of speed per second. It is not possible to be any more precise because the unit of speed (kilometres per hour, miles per hour, metres per second) is unspecified.
What is a cars acceleration if it increases its speed from 5 m s to 20 m s in 3 s?
The answer will be 5 m/sec/sec 300m/sec - 200m/sec divided by 20 seconds will get you 100m/sec divided by 20 seconds, which then equals 5
How long would it take a car to accelerate from 10 MPH to 75 MPH if its acceleration is 20 MPHs?
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
A cars velocity changes from 20 ms to 50 ms 10 seconds later What is the cars average acceleration?
3 ms-2
How long would it take a car to accelerate from 15 MPH to 75 MPH if its acceleration is 20 MPH?
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds
What is colder 20 mph or 13 mph?
20 MPH would be colder, as the increased speed increased heat transfer away from the moving object.
What is the acceleration of a car that moves at a constant velocity of 20 meters per second?
-- "Acceleration" is any change of velocity.-- "Velocity" is a speed and its direction.-- "20 meters per second" is a speed, not a velocity, because it doesn't mention a direction.-- We don't have enough information to say anything about that car's acceleration.If, for example, it happens to be moving at a constant speed of 20 meters per secondon a circular track, then it has plenty of acceleration.
In a test run a certain car accelerates uniformly from zero to 24 meters per second in 2.95s what is the magnitude of the cars acceleration?
The car's uniform acceleration is (change in speed) divided by (change in time) = (24 m/s) / (2.95 s) = 8.1356 meters/sec2. Call this number ' A ' for acceleration. Change in speed = ( A ) times (time) Time = (change in speed) / A = (20 - 10) / A = 10/A = 0.81356 seconds (rounded)
A cars velocity changes from 20 m s to 50 m s 10 seconds later What is the cars average acceleration?
5 m/s2 east
What is a cars acceleration if its speed increases from 50 kilometers per hour to 80 kilometers per hour in six seconds?
well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s
If a runner increases her velocity from 2 meters per second to 4 meters per second over a period of 20 seconds what is the acceleration?
Magnituide of acceleration = (change in speed) divided by (time for the change)= (final speed - initial speed) divided by (time for the change)= 2/20 = 0.1 meter per second2Note that this is the magnitude of the acceleration, obtained by working with the speeds.We don't know the initial or final velocities, because there's no information regarding directions.Similarly, we only know the magnitude of the acceleration, not its direction.
How do you find instantaneous acceleration from 5 m s to 25 m s is 4 seconds What is the rate?
Acceleration = rate of change of speed = (change of speed) / (time interval) = (25 - 5) / 4 = 20/4 = 5 m/s2
