A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
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.
What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
A race car starting from rest accelerates uniformly at a rate of 4.90 meters per second what is the cars speed after it has traveled 200 meters?
Acceleration cannot be measured in metres per second. There is, therefore a fundamental problem with the question.
Which one of the following quantities is measured by by meters per second squared?
Meters per second squared (m/s²) measures acceleration, which is the rate of change of velocity per unit time. It indicates how quickly an object's speed is increasing or decreasing. For example, if an object accelerates at a rate of 5 m/s², its velocity increases by 5 meters per second for every second that passes.
What is the acceleration of an object that travels 8 meters in 1 second 8 meters in the 2nd second and 8 meters in the 3rd second?
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.
To pass a truck a car initially traveling 25 meters per second accelerates at a constant rate of 3 meters per second squared after 6 seconds how fast is the car traveling?
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.
What is the force that accelerates objects at 9.80665 meters per second squared towards Earth?
gravity
What is si unit of uniform acceleration?
The SI unit for acceleration is the meter per second squared (m/s 2).
A car accelerates to pass a truck going from 20 meters per second to 29 meters per second in 3 seconds What is the acceleration?
3 m/s2
A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is blankmeters/second2?
The acceleration of the body is 3 m/s²
A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
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.
How many meters does a car travel that starts from rest and accelerates for 4.7 seconds with an acceleration rate of 3.6 meters per second squared?
60.912 meters in that time
What is the rate of the gravity accelerates objects on earth?
The acceleration due to gravity alone on Earth is about 9.81 meters per second-squared.
Why does speed increase?
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.
What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
A race car starting from rest accelerates uniformly at a rate of 4.90 meters per second what is the cars speed after it has traveled 200 meters?
Acceleration cannot be measured in metres per second. There is, therefore a fundamental problem with the question.
A body falling freeling from a height towards the earth moves with uniform?
acceleration due to gravity, causing it to increase its speed at a constant rate. This acceleration is approximately 9.81 meters per second squared.
