A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is meters/second2.
Question
A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is meters/second².
Solution
The acceleration of an object is calculated by the formula:
Acceleration = (Final velocity - Initial velocity) / Time
In this case, the final velocity (v_f) is 16 meters/second, the initial velocity (v_i) is 4 meters/second, and the time (t) is 4 seconds.
So, the acceleration (a) would be:
a = (v_f - v_i) / t a = (16 m/s - 4 m/s) / 4 s a = 12 m/s / 4 s a = 3 m/s²
So, the car's acceleration is 3 meters per second squared.
