Acceleration = (change in speed) / (time for the change) = (10-4) / 4 = (6/4) = 1.5 m/s2
The mass of the object makes no difference at all.

Erin speeds up from 0 to 8 meters per second in 4 seconds what is her acceleration?
2 m/s2. Acceleration is (speed gained)/(time taken), In this case 8/4=2
What is the average speed of a car that speeds up from 60 miles per hour to 70 miles per hour in 8 seconds?
The answer depends on whether the rate of acceleration is uniform. There is no indication in the question that it is.
How does constant velocity differ from constant acceleration?
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
A car traveling at 8 meters per second due north speeds up to 10 meters per second in the same direction If it takes the car 5 seconds to change its velocity what is the car's acceleration?
Magnitude of acceleration = (change in speed) / (time for the change) = 2/5 Acceleration = 0.4 meters per second2 north
What is the acceleration of a 3 kg mass if a force of 14.4 N is used to move the mass?
Acceleration = force/mass:14.4 / 3 = acceleration of 4.8meters per second squared.
An unbalanced force of 10 newtons acts on a 20 kilogram mass for 5 seconds the acceleration of the mass is?
Force = (Mass) x (Acceleration)Acceleration = (Force) / (mass) = 10/20 = 1/2 meter per second2The length of time doesn't matter. The acceleration is constant as long as the force continues.

A race car driver speeds up from 60 miles per hour to 90 miles per hour in 3 seconds what was her acceleration in mphsec?
acceleration =(90-60)/(3)=10 mphs=10 mile per hour sec Ahmad Jordan

What is the dimension of gravitation?
Gravitation can be expressed as either an acceleration or a force per unit mass.[Acceleration] = [Length/Time2][Force per unit mass] = [mass-length/Time2] per [mass] = [length/time2]
What is the average net force if a car with 1000kg reaches the speed of 28 meters per seconds in 7 seconds?
Acceleration = (change in speed) / (time) = 28/7 = 4 meters per second2Force = (mass) x (acceleration) = (1,000 x 4) = 4,000 kg-m/sec2 = 4,000 Newtons.
What happens to acceleration if the mass is increased and due to gravity?
The acceleration of an object due to gravity does not depend on the mass. Close to Earth's surface, this acceleration is about 9.8 meters per second per second.
Find mass given force and acceleration?
Force = mass x acceleration. Mass must be in kilograms and acceleration must be in meters per second squared.

Acceleration = force/mass:14.4 / 3 = acceleration of 4.8meters per second squared.
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.
