8. A car travels at a constant velocity of 70 mph for one hour. By the end of the second hour, the car’s velocity was 60 mph. At

Mrac [35]

<u>Answer:</u>

Positive acceleration is in third hour and negative acceleration is in second hour.

<u>Explanation:</u>

Velocity of car in first hour = 70 mph

Velocity of car in second hour = 60 mph

Velocity of car in third hour = 80 mph

Acceleration = Change in velocity / Time

Acceleration in second hour = (60 - 70)/1 = -10 mph²

Acceleration in third hour = (80 - 60)/1 = 20 mph²

So positive acceleration is in third hour and negative acceleration is in second hour.
