An independent variable can be define as the variable which can be changed in an experiment. It can be manipulated manually. The effect of such alteration and manipulation can be observed on the dependent variable.  

The dependent variable is the one which changes due to the changes and alteration done by the experimenter on the independent variable.

Answer: vf = 51 m/s

d = 112 m

Explanation: Solution attached:

To find vf we use acceleration equation:

a = vf - vi / t

Derive to find vf

vf = at + vi

Substitute the values

vf = 3.5 m/s² ( 8.0 s) + 23 m/s

= 51 m/s

To solve for distance we use

d = (∆v)² / 2a

= (51 m/s - 23 m/s )² / 2 ( 3.5 m/s²)

= (28 m/s)² / 7 m/s²

= 784 m/s / 7 m/s²

= 112 m
