Calculate the acceleration of a stunt driver
Calculating Acceleration
To calculate the acceleration of a car, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Given the data provided:
- Initial velocity (u) = 40 m/s
- Final velocity (v) = 35 m/s
- Time (t) = 0.12 s
Substitute these values into the formula:
acceleration = (35 m/s - 40 m/s) / 0.12 s
acceleration = -5 m/s / 0.12 s
acceleration = -41.67 m/s²
Therefore, the acceleration of the car is approximately -41.67 m/s².
