<h3>Answer: True </h3>

As the object falls down, it pushes air aside, and the air pushes back (newton's 3rd law) so the air slows down the object a very tiny amount. This causes friction. The friction produces some heat as well.

The average speed of Frank's car is 2 m/s and the average speed of Noah's car is 1.8 m/s.

<u>Explanation:</u>

Average speed is the measure of total distance covered at different time period. Since, the formula used for calculating the average speed is the ratio of total distance covered by each car to the time taken to cover that distance.

As there is only one set of data i.e., distance and time, the average speed will be equal to the speed of the car.

So in this case, the total distance covered by franks car is 300 cm = 3 m in 1.5 s. Then, the average speed will be

$Avg. S_{frank} = \frac{Total\ distance\ rolled\ by\ his\ car}{Time\ taken}$
