Final answer:
Acceleration is the rate of change of velocity. To calculate the acceleration of a car that goes from rest to a speed of 72 km/h in 10s, convert the final velocity to m/s and plug into the acceleration formula.
Explanation:
Acceleration is the change in velocity over time. To find the acceleration of the car, you can use the formula: acceleration = (final velocity - initial velocity) / time. Converting the final velocity from km/h to m/s, you get 20 m/s. Substituting the values into the formula, you can calculate the acceleration.
