A car travels in a straight line for 4.8 h at a
constant speed of 57 km/h .
What is its acceleration?
Answer in units of m/s
11.875
To find the acceleration of the car, we can use the equation:
Acceleration (a) = Change in velocity (Δv) / Time (t)
Since the car is traveling at a constant speed, the velocity (v) remains the same, and therefore the change in velocity (Δv) is zero.
So, the equation becomes:
Acceleration (a) = 0 / Time (t)
Since there is no change in velocity, the acceleration of the car is zero.
Therefore, the acceleration of the car is 0 m/s².
