Answer:
$ 1,781.53
Explanation:
The future value of the 5-year CD can be determined by using the future value formula stated below:
FV=PV*(1+r)^n
FV is the future value which is expected future amount after 5 years
PV is the initial amount used in purchasing the CD i.e $1500
r is the rate of return on the CD on an annual basis which is 3.5%
n is the number of years the investment would last which is 5 years
FV=$1500*(1+3.5%)^5
FV=$1500*1.187686306
FV=$ 1,781.53

Displacement = 180m due east
Time taken = 9s
Unknown:
Average velocity of the truck = ?
Solution:
The average velocity is the displacement divided by the time taken;
Average velocity =
Insert the parameters and solve;
Average velocity =
= 20m/s due east
