Chapter 1.1, Problem 19ES

For inclined plane $1$, the distance a ball rolls in the 1^st second is $8$ centimeters. Think of this distance as $1$ unit. That is, for inclined plane $1$, $1$ unit $=$ 8 centimeters. Determine how farin terms of units a ball will roll, on inclined plane $1$, in the following time intervals.

a. 2^nd second: $t=1$ to $t=2$ seconds

b. 3^rd second: $t=2$ to $t=3$ seconds

c. 4^th second: $t=3$ to $t=4$ seconds

d. 5^th second: $t=4$ to $t=5$ seconds
