A person walks a distance of 3.0 km due south and then a distance of 2.0 km due east.
If the walk lasts for 3.0 h find
(a) the average speed for the motion;
(b) the average velocity.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333
