To solve the problem, we will calculate the average velocity of the car over the first 20 seconds of its motion. Here’s a step-by-step breakdown of the solution: ### Step 1: Calculate the displacement during the first 18 seconds The car covers a distance of 420 meters in the first 18 seconds. Since it is moving in a straight line, the displacement is also 420 meters. **Displacement after 18 seconds = 420 m** ### Step 2: Determine the motion after 18 seconds ...
