How long would it take a drag racer to increase her speed from 10 meters per second to 20 meters per second if her car accelerates at a uniform rate of 15 meters per second square?

Speed=15t + 10 The 15t accounts for acceleration, while the initial velocity of 10 is accounted for by +10. As such, the amount of time (t) for the car to reach 20m/s is 2/3s.

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.
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.
A car accelerates uniformly in a straight line from rest at the rate of 2.2 ms2 What is the speed of the car after it has traveled 62 m Answer in units of ms?
At the end of 7.508 seconds, the car has traveled 62 meters, and it's speed is 16.517 meters per second.
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
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 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 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
A car initially traveling at a speed of 16 meters per second accelerates uniformily to a speed of 20 meters per second over a distance of 36 meters what is the magnitude of her acceleration?
The car's final velocity will be 37.68 meters per second / 84.3 mph
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!)
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.
What is expressed in meters per second per second?
It is acceleration that is measured in distance per unit of time per unit time, or in meters per second per second, as the question asked. The only thing missing is the direction vector.
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.
