The acceleration of a car that speeds up from 12 meters per second to ...
To find the acceleration of a car, we can use the formula:
Acceleration (a) = (Final velocity - Initial velocity) / Time
Given:
Initial velocity (u) = 12 m/s
Final velocity (v) = 30 m/s
Time (t) = 15 seconds
Substituting the given values into the formula:
Acceleration (a) = (30 m/s - 12 m/s) / 15 s
Acceleration (a) = 18 m/s / 15 s
Acceleration (a) = 1.2 m/s^2
Therefore, the acceleration of the car is 1.2 m/s^2.
Explanation:
- The initial velocity of the car is given as 12 m/s.
- The final velocity of the car is given as 30 m/s.
- The time taken for the car to accelerate from the initial velocity to the final velocity is given as 15 seconds.
To calculate the acceleration, we use the formula which states that acceleration is equal to the change in velocity divided by the time taken. In this case, the change in velocity is the final velocity minus the initial velocity.
To calculate the change in velocity, we subtract the initial velocity from the final velocity:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 30 m/s - 12 m/s
Change in velocity = 18 m/s
Then, we divide the change in velocity by the time taken:
Acceleration = Change in velocity / Time
Acceleration = 18 m/s / 15 s
Acceleration = 1.2 m/s^2
Therefore, the acceleration of the car is 1.2 m/s^2.
Acceleration (a) = (Final velocity - Initial velocity) / Time
Given:
Initial velocity (u) = 12 m/s
Final velocity (v) = 30 m/s
Time (t) = 15 seconds
Substituting the given values into the formula:
Acceleration (a) = (30 m/s - 12 m/s) / 15 s
Acceleration (a) = 18 m/s / 15 s
Acceleration (a) = 1.2 m/s^2
Therefore, the acceleration of the car is 1.2 m/s^2.
Explanation:
- The initial velocity of the car is given as 12 m/s.
- The final velocity of the car is given as 30 m/s.
- The time taken for the car to accelerate from the initial velocity to the final velocity is given as 15 seconds.
To calculate the acceleration, we use the formula which states that acceleration is equal to the change in velocity divided by the time taken. In this case, the change in velocity is the final velocity minus the initial velocity.
To calculate the change in velocity, we subtract the initial velocity from the final velocity:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 30 m/s - 12 m/s
Change in velocity = 18 m/s
Then, we divide the change in velocity by the time taken:
Acceleration = Change in velocity / Time
Acceleration = 18 m/s / 15 s
Acceleration = 1.2 m/s^2
Therefore, the acceleration of the car is 1.2 m/s^2.
