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

A = 300 mi/s - 200 mi/s/20 s - 0 s
Acceleration = 5 miles per second squared

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
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)
Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds what is her acceleration?
It is 0.1 metre per second-squared.
What Acceleration is defined as a change in velocity over time. If a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds what is her acceleration?
It is 0.1 metre per second-squared.
If speed increases and time remains the same what happens to distance?
By increasing speed over a fixed period of time, you increase the distance you travel in that period of time. If you drive 20 mph for an hour, you go 20 miles. If you drive 30 mph for that same hour, you go 30 miles. Just like you knew you would.
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 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 car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
5 m/s2
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.
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.
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.
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
How does increasing the temperature affect the speed of sound in the air?
Speed of sound increases, when temperature increases. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
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
