A car travels in a straight line for 5.1 h at a

constant speed of 94 km/h .
What is its acceleration?

constant speed means zero acceleration

the acceleration would be 0 because the speed is constant!

To find the acceleration of the car, we will first need to understand the concept of acceleration. Acceleration is the rate at which an object changes its velocity.

In this case, the car is traveling in a straight line at a constant speed. Since the car is not changing its speed, the acceleration is zero. Acceleration only occurs when there is a change in velocity. If the car were to speed up or slow down, we could calculate the acceleration using the change in velocity over time.

Therefore, in this situation, the acceleration of the car is 0.
