The car’s average acceleration between and is .
The car’s average acceleration between and is .
Further Explanation:
The acceleration is the rate of change in the velocity that is difference between the final velocity and initial velocity divided by the difference in the final time and initial time.
If the initial velocity of the object is less than the final velocity then the body must accelerate but when the initial velocity of the object is more than the final velocity then the body must decelerate.
Given:
The data for fastest cars made in U.S. in terms of time (s) and speed (mi/h) is:
At speed is , speed is , speed is , speed is .
Concept:
The speed in mi/h can be written in terms of m/s as:
The expression for the average acceleration is:
Here, is the average acceleration, is the final velocity, is the initial velocity, is the initial time and is the final time.
Part (1)
Substitute for , for , for and for in the above equation.
Therefore, the car’s average acceleration between and is .
Part (2)
Substitute for , for , for and for in the above equation.
Therefore, the car’s average acceleration between and is .
