Final answer:
The acceleration of the car is 2.311 m/s².
Step-by-step explanation:
To calculate acceleration, we can use the formula:
Acceleration = (Final Velocity - Initial Velocity) / Time
Given that the initial velocity of the car is 2.3 m/s, the final velocity is 27 m/s, and the time is 9.8 seconds, we can substitute these values into the formula:
Acceleration = (27 - 2.3) / 9.8 = 2.311 m/s²
Therefore, the acceleration of the car is 2.311 m/s².
To calculate the acceleration of a car, we use the formula a = (v_f - v_i) / t, where v_i is the initial velocity, v_f is the final velocity, and t is the time taken. In the given problem, a car accelerates from 2.3 m/s to 27 m/s in 9.8 seconds.
The acceleration a can be calculated as follows:
a = (27 m/s - 2.3 m/s) / 9.8 s = 24.7 m/s² / 9.8 s = 2.52 m/s².
Therefore, the car's acceleration is 2.52 m/s².
