a racing car accelerates from rest to 30m/s in 6.0s what is her average acceleration?
the answer in the book is 0.5m/s^2
To calculate the average acceleration, we need to use the formula:
Average acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is 0 m/s, the final velocity is 30 m/s, and the time is 6.0 s. Plugging these values into the formula:
Average acceleration = (30 m/s - 0 m/s) / 6.0 s
Average acceleration = 30 m/s / 6.0 s
Average acceleration = 5 m/s
The answer you have provided, 0.5 m/s², seems incorrect based on the given information. Please double-check the values and equations used in your book.
Did the car accelerate to 30 miles per second? That is quite a fast car!
The formula for average acceleration is (change in velocity) divided by (change in time).
I hope this helps.
you have two ordered pairs of the form (t,v)
namely (0,0) and (6,30)
average acceleration = change in velocity / change in time
= (30-0)/(6-0) (m/s) / s
= 5 m/s^2
I suspect a typo in your book
