If there were 49 cars in a line that stretched 528 feet, what is the average car length? assume that the cars are lined up bumper-to-bumper
Answer: We are given there are 49 cars
Also these 49 cars are in a line stretched 528 feet.
Now the average length of the car is:
Average length = 
=
Therefore, the average length of car is 10.78 feet
To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:

0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s
