A car traveling at 20 m/s reaches 60 m/s in 4 seconds traveling in a straight line. The car has an average acceleration of m/s2.
Question
A car traveling at 20 m/s reaches 60 m/s in 4 seconds traveling in a straight line. The car has an average acceleration of m/s².
Solution
The acceleration of an object is calculated by the formula:
Acceleration = (Final velocity - Initial velocity) / Time
In this case, the final velocity (Vf) is 60 m/s, the initial velocity (Vi) is 20 m/s, and the time (t) is 4 seconds.
So, the acceleration (a) would be:
a = (Vf - Vi) / t a = (60 m/s - 20 m/s) / 4 s a = 40 m/s / 4 s a = 10 m/s²
Therefore, the car has an average acceleration of 10 m/s².
