What is a car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
5 m/s2
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 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 initially traveling at a speed of 16 meters per second accelerates uniformily to a speed of 20 meters per second over a distance of 36 meters what is the magnitude of her acceleration?
The car's final velocity will be 37.68 meters per second / 84.3 mph
What is a car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
5 m/s2
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
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.
What is the acceleration if the velocity increases by eighty meters per second in twenty seconds?
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2
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.
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
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
How do you calculate the acceleration if stationary car that accelerates to 20meterper second travelling in 5 seconds?
Remember the equation for acceleration. a = (v - u ) / t Were a = acce;leration v = final speed ( 20 m/s) u = initial speed ( 0 m/s) t = time ( 5 s) Substituting a = ( 20 m/s - 0 m/s) / 5s a = 20m/s / 5s a = 4 m /s^2
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.
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 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
If an object has an acceleration of twenty centimeters a second squard what do you know about how its speed changes over time?
It increases by 20 centimetres per second in the given direction for each second that elapses.
