Speed = (initial speed) plus (acceleration) x (time) =
0 + (5) x (3) =
15 meters per second.

What is the acceleration of a car that accelerates from 44ms to 88ms over a period of 11 seconds?
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
What is the average acceleration of a car that goes from rest to 60 mph in 8 seconds?
The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is a car's acceleration if it accelerates from 25 km to 55 km in 30 seconds?
Acceleration is a measure of the rate of change of velocity.Assume the question is, "A car accelerates from 25 kph to 55 kph in 30 sec what is its acceleration?The formula for this calculation is v = u + ft : v = final velocity, u = initial velocity, f = acceleration, t = time. But all measurements have to be in related units. As speed is measured in kph then time needs to be converted to hours. 30 seconds = 1/2 minute = 1/120 hour55 = 25 + f/120 : 30 = f/120 : f = 30 x 120 = 3600 kph2As there are 3600 seconds in 1 hour then the acceleration can be stated as 1 kps2.
An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.
What is the acceleration of a car that accelerates from 44ms to 88ms over a period of 11 seconds?
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/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 the final velocity f a car that accelerates from rest at 9ftsecond squared for 8 seconds?
Speed = (acceleration) x (time) = 9 x 8 = 72 ft/sec
What is the average acceleration of a car that goes from rest to 60 mph in 8 seconds?
The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.
A car accelerates from rest and accelerates at 3 ms-2 how long it will take to reach a velocity of 30ms-1?
Acceleration = (change in speed) / (time for the change)3 = (30) / (time)3 x (time) = 30time = 30/3 = 10 seconds
What accelerates on a speed time graph?
The slope at each point on a speed/time graph is themagnitude of acceleration at that point in time.
A vehicle accelerates uniformly from a speed of 4.0ms to a speed of 12ms in 6.0s. What is the vehicles acceleration?
4/3 ms-2.
What does accelerating?
It means that something accelerates, or is subject to acceleration. In popular language, "acceleration" is often understood to mean that the speed increases. In physics, acceleration is any change of velocity.
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 the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What accelerates while traveling at constant velocity?
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
