6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
Acceleration cannot be measured in metres per second. There is, therefore a fundamental problem with the question.
Acceleration is the increase in speed from one unit of time to the next, so the described object has no acceleration. Its speed is constant.
At the end of 7.508 seconds, the car has traveled 62 meters, and it's speed is 16.517 meters per second.
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
gravity
The SI unit of uniform acceleration is meters per second squared (m/s^2). It represents the increase in velocity by one meter per second each second.
The acceleration of the body is 3 m/s²
3 m/s2
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
60.912 meters in that time
The acceleration due to gravity on Earth is about 9.81 m/s^2. This means that every second, objects in free fall near Earth's surface will increase their speed by 9.81 meters per second.
Speed increases when a body accelerates under the influence of a force. Newton's second law: acceleration= force/mass. Acceleration is the rate of change of speed over a period of time. For example if you drop an object, it's speed increases by 9.8 meters per second every second.

acceleration due to gravity, causing it to increase its speed at a constant rate. This acceleration is approximately 9.81 meters per second squared.
