A car travels in a straight line for 4.9 h at a constant speed of 73 km/h .

What is its acceleration?
Answer in units of m/s2

0.012m/s2

To find the acceleration of the car, we need to use the equation:

acceleration = change in velocity / time

Since the car is traveling at a constant speed, its velocity does not change. Therefore, the change in velocity is zero.

The formula for acceleration simplifies to:

acceleration = 0 / time

The car traveled for 4.9 hours, so we can substitute the value into the equation:

acceleration = 0 / 4.9

Any number divided by zero is undefined. Therefore, the acceleration of the car is undefined (or zero) as its velocity does not change.
