Question

A car has an acceleration of 1m/sec. What is the change in its velocity after every 3 seconds?

Answer 1

The change in velocity of a car can be calculated using the formula:

$\Delta v=a\cdot \Delta t$

Where:

• $\Delta v$ represents the change in velocity
• $a$ is the acceleration
• $\Delta t$ is the change in time

In this case, the car has an acceleration of 1 m/s², and the change in time is 3 seconds. Plugging these values into the formula, we can calculate the change in velocity:

$\Delta v=1\text{m/s²}\cdot 3\text{s}=3\text{m/s}$

Therefore, the change in velocity of the car after 3 seconds is 3 m/s.
