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 average speed of an ant that crawls 1 mile in 45 seconds?
Extremely fast: 1 hour = 3600 seconds speed = distance/time = 1 mi / 45 s = 1/45 mi/s = 1/45 mi/s x 3600 s/hr = 3600/45 mi/hr = 80 mph!
What is the range of time for these five cars 4 minutes 30 seconds 5 minutes 12 seconds 4 minutes 24 seconds 4 minutes 51 seconds 5 minutes 3 seconds?
The range is the highest - the lowest. 5:12 - 4 mins 24 secs. This is 48 seconds
Freeway speed limit is 65 mph cars are driving 70 mph what mph is it legal to drive?
It would be 65 MPH.
If a car travels 30 miles in 1 hour and 30 minutes what is the cars speed?
.66667 miles per hour
Two cars are 15 kms apart One is turning at a speed of 50kmph and the other at 40kmph How much time will it take for the two cars to meet?
If you mean traveling (which is different from turning), then they will meet in 15 minutes. The total of their speeds is 90kmph, which gives you 1.5k per minute. Mulitply that by 10 and you have 15k, the total distance they need to travel.
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
How are acceleration and speed different?
Acceleration is the rate of change of an object's velocity over time, while speed is the rate at which an object covers distance. In other words, acceleration measures how quickly an object's speed is changing, while speed indicates how fast an object is moving at a specific point in time.
If a cars velocity changes from 0 ms to 30 ms 10 seconds later its average acceleration is?
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
What is the cars acceleration?
Bugatti Veyron Super Sport 0-60mph in 2.4 seconds
How do you determine a cars final speed after acelerating for three seconds?
Using the equation of motion v = u + at. v-the final velocity, u - initial velocity a- acceleration and t-the time.
What is a cars acceleration if it increases its speed from 5 m s to 20 m s in 3 s?
The acceleration of the car would be (20 m/s - 5 m/s) / 3 s = 5 m/sĀ².
A cars velocity changes from 20 ms to 50 ms 10 seconds later What is the cars average acceleration?
3 ms-2
When riding in a car we can sense changes in speed or direction through the forces the car applies on us. Do we wear seat belts in cars and airplanes to protect us from speed or from acceleration?
Acceleration
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
How many seconds between cars?
At least 2. At freeway speed, 3-5.
How do you spell xlr8tion?
ACCELERATION : in the process of increasing velocity or speed, especially continuously (e.g. gravity, race cars).
