Describe an instance where you might use standard rounding. describe an instance where you might use order of magnitude estimation. If you did this on part 2 of the test, plz help me out,( do not delete answer or give me false hope, no links. Because I can’t open them, if you have a link, go in that link and copy and paste your answer) I really need general help here.

Using the following formulas:

Range = [ Vo^2 * sin 2*theta ]/g

Height = [ Vo^2 * sin theta^2 ]/g

Since the relation between Range and height is given: ( R = 3H ), the 2 equations can be equated in terms of Vo^2 so that the only remaining unknown variable left will be the angle. This is done as shown:

( g*Range )/(sin 2*theta) = Vo^2
( g*Height )/(sin theta^2) = Vo^2


( g*Range )/(sin 2*theta) = ( g*Height )/(sin theta^2)

Applying Range = 3*Height:
( g*3*Height )/(sin 2*theta) = ( g*Height )/(sin theta^2)

substituting given values while Height cancels out:

( 9.8*3 )/(sin 2*theta) = ( 9.8 )/(sin theta^2)
Angle theta = 33.67 degrees
