A car travels in a straight line for 2.8 h at a
constant speed of 53 km/h .
What is its acceleration?
Answer in units of m/s

constant speed means zero acceleration!

Acceleration is the rate at which the velocity of an object changes over time. In this case, the car is traveling at a constant speed of 53 km/h for 2.8 hours.
To find the acceleration, we need to use the formula:
acceleration = change in velocity / time
However, since the car is traveling at a constant speed, the velocity does not change, so the change in velocity is 0. Therefore, the acceleration in this case is also 0 m/s².
This means that the car is not accelerating or decelerating, and its velocity remains constant throughout the 2.8 hours.
