In the record setting race, a dragster reached a velocity of 145.08 m/s in 4.48s. What was the dragsters average acceleration? Assume that the direction of the velocity is positive.
Thank you and can you show me how to do the other questions I post
To find the average acceleration of the dragster, we can use the formula:
Average acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is zero since we are assuming that the dragster started from rest. So the formula becomes:
Average acceleration = (final velocity - 0) / time
Plugging in the given values:
Average acceleration = (145.08 m/s - 0) / 4.48 s
Calculating:
Average acceleration = 145.08 m/s / 4.48 s ≈ 32.44 m/s²
Therefore, the dragster's average acceleration was approximately 32.44 m/s².
To find the average acceleration, we can use the formula:
average acceleration = (final velocity - initial velocity) / time
In this case, the final velocity is 145.08 m/s, the initial velocity is 0 m/s (since it starts from rest), and the time is 4.48 seconds.
Using the formula, we can calculate the average acceleration as follows:
average acceleration = (145.08 m/s - 0 m/s) / 4.48 s
Simplifying the calculation:
average acceleration = 145.08 m/s / 4.48 s
Calculating the numerical value:
average acceleration ≈ 32.4 m/s²
Therefore, the dragster's average acceleration is approximately 32.4 m/s².
