A car goes from 4.47 m/s to 17.9 m/s in 3 seconds.
Calculate the acceleration of the car.
a = ∆v/∆t = (17.9-4.47 m/s) / (3-0)s = (13.43 m/s)/(3s) = 4.47 m/s^2
Full formula
Correct values inserted into the formula from the word problem
To calculate the acceleration of the car, you need to use the following formula:
acceleration (a) = (final velocity - initial velocity) / time
In this case, the final velocity is 17.9 m/s, the initial velocity is 4.47 m/s, and the time is 3 seconds.
Plugging these values into the formula, we get:
a = (17.9 m/s - 4.47 m/s) / 3 s
Now, we can calculate the acceleration:
a = 13.43 m/s / 3 s
a = 4.47667 m/s²
Therefore, the acceleration of the car is approximately 4.48 m/s².
