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.
