Final answer:
The average acceleration from 0 to 30 mi/hr is 8.57 mi/hr^2, from 30 to 60 mi/hr is 7.89 mi/hr^2, and from 0 to 60 mi/hr is also 7.89 mi/hr^2.
Step-by-step explanation:
To calculate the average acceleration from 0 to 30, we can use the formula:
Acceleration = (Final velocity - Initial velocity) / Time
For the first scenario, where the car accelerates from 0 to 30 mi/hr in 3.5 seconds:
Initial velocity = 0 mi/hr, Final velocity = 30 mi/hr, Time = 3.5 seconds
Plugging the values into the formula: (30 - 0) / 3.5 = 8.57 mi/hr^2
For the second scenario, where the car accelerates from 0 to 60 mi/hr in 7.6 seconds:
Initial velocity = 0 mi/hr, Final velocity = 60 mi/hr, Time = 7.6 seconds
Plugging the values into the formula: (60 - 0) / 7.6 = 7.89 mi/hr^2
For the third scenario, where the car accelerates from 0 to 60 mi/hr:
Initial velocity = 0 mi/hr, Final velocity = 60 mi/hr, Time = 7.6 seconds
Plugging the values into the formula: (60 - 0) / 7.6 = 7.89 mi/hr^2
