Question

1. what is the acceleration of a car that maintains a constant velocity of 100 km/h for 10 seconds?

Explanation:

Step1: Recall acceleration formula

Acceleration $a=\frac{\Delta v}{\Delta t}$, where $\Delta v$ is change in velocity and $\Delta t$ is change in time.

Step2: Determine change in velocity

The car has a constant velocity of 100 km/h. So, $\Delta v = 0$ km/h.

Step3: Calculate acceleration

Substitute $\Delta v = 0$ km/h into the acceleration formula. Since $\Delta t=10$ s, $a=\frac{0}{\Delta t}=0$ km/h/s.

Answer:

0 km/h/s
