Answer:
hello your question lacks some information hence I will provide a more general answer
answer :
The expression is ; D = a + ar
Step-by-step explanation:
An expression illustrating the total vertical distance travelled by a body from rest ( "spot it was first sighted" ) as quoted in the question. can be written as
D = a + ar
where D = Total vertical distance travelled
a = start term ( initial height )
r = common ratio
