∙ 11y agoUnknown: final velocity, vf
Known:
initial velocity, vi = 0m/s
time, t = 15.0s
average acceleration, a = 2.40m/s2
Equation:
vf = vi + at
Solution:
vf = 0 + 2.40m/s2 x 15.0s = 36.0m/s

∙ 11y agowhat 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)
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
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.
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Converting the initial velocity of 0 km/hr to m/s and final velocity of 60 km/hr to m/s, and plugging in the values, we get the acceleration to be 2 m/s^2.
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)
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
The answer will depend on its acceleration.
To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
the acceleration of the car is 1.179m/s/s given the formula provided.
The average acceleration during the time interval from 0 to 10 seconds is the change in velocity divided by the time interval. If you provide the initial and final velocities during this time interval, we can calculate the average acceleration for you.
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
The car's average acceleration is the change in velocity divided by the time taken. Here, the change in velocity is from 14 m/s to 25 m/s which is 11 m/s. Given that the time taken is 10 seconds, the average acceleration of the car is 1.1 m/s^2.
