Final answer:
The time it takes for the car to reach a speed of 122 km/h is approximately 10.75 seconds.
Explanation:
To find the time it takes for the car to reach a speed of 122 km/h, we can use the equation:
v = u + at
Where:
- v is the final velocity (122 km/h = 34.4 m/s)
- u is the initial velocity (0 m/s)
- a is the acceleration (3.2 m/s²)
- t is the time taken
Rearranging the equation to solve for t:
t = (v - u) / a
Substituting the given values:
t = (34.4 m/s - 0 m/s) / 3.2 m/s²
t = 10.75 s
So, the time it takes for the car to reach a speed of 122 km/h is approximately 10.75 seconds.
