Answer: 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.
Step-by-step explanation:
To calculate the time it takes for a car with an acceleration of 2 m/s^2 to go from a velocity of 10 m/s to a velocity of 30 m/s, we can use the equation:
time = (final velocity - initial velocity) / acceleration
In this case:
time = (30 m/s - 10 m/s) / 2 m/s^2
time = 20 m/s / 2 m/s^2
time = 10 s
Therefore, it takes 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.
