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
What speed is space shuttle at 4 seconds after launch?
At 4 seconds after launch, the space shuttle typically reaches a speed of around 100 mph (160 km/h) as it accelerates rapidly in the initial phase of its journey into space.
What object accelerates and changes speed?
An object accelerates when there is a net force acting on it, causing it to change speed. The acceleration can be in the form of speeding up, slowing down, or changing direction.
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
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 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.
What is acceleration and what atr two conditions that can change when an object accelerates?
Acceleration is the rate at which the velocity of an object changes over time. Two conditions that can change when an object accelerates are its speed (magnitude of velocity) and direction of motion.
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.
Can an object accelerates when its speed is constant?
No, if an object's speed is constant, then it is not accelerating. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object's speed is constant, it means there is no change in velocity and therefore no acceleration.
What is the acceleration of a skateboarder traveling 12m per sec?
Since acceleration is the rate of change of velocity, we would need more information about how the skateboarder's speed is changing over time in order to calculate the acceleration. Simply knowing the skateboarder's speed of 12 m/s is not enough to determine the acceleration.
