Calculating the Acceleration of a Car
Understanding Car Acceleration
Acceleration is an important concept in physics that measures the rate of change in velocity of an object. When a car accelerates uniformly, it means that the velocity of the car increases by the same amount in equal time intervals.
The Formula for Acceleration
The formula to calculate acceleration is:
a = (v - u) / t
Where:
- a = acceleration
- v = final velocity
- u = initial velocity (in this case, the car starts from rest)
- t = time taken to reach the final velocity
Given Data
A car accelerates uniformly from rest to 25 m/s over a distance of 30 meters. We need to find the acceleration of the car.
Calculating Acceleration
Given that the car starts from rest, the initial velocity u is 0 m/s. The final velocity v is 25 m/s, and the distance s is 30 meters.
Answer:
a = (v2 - u2) / 2s
a = (252 - 0) / 2*30
a = 625 / 60
a = 25/24 m/s2
Explanation:
Based on the calculations, the acceleration of the car is 25/24 m/s2.
What is the acceleration of the car?
a = 25/24 m/s^2
Explanation: I'm going to assume you mean the final velocity is 25m/s.
v^2 = u^2 + 2as
625 = 0 + 2a300
a = 25/24 m/s^2 or 1.0416 m
