g (9.8) in exam 1

[Ken]

do they assume u know how to calculate mentally what 4g, 5g and so on into number form? many of the practice exams i've done assume so

[fredrick]

Convert 9.8 to and it will easyile cancel out.

EDIT: id also like to know if leaving the answer like N is sufficient

[Ken]

hah thanks for that

[Mao]

remember your arithmetics

9.8 * 4 = 9*4 + 0.8 * 4 = 36 + 3.2 = 39.2
etc

[Collin Li]

Remember that 9.8 is easily divisible by 7. Notice how you always divide 9.8 by 2, and it's 4.9?

4.9 divided by 7 is obviously 0.7, and so 9.8 divided by 7 is 1.4

(Some of my experiences with )

[Matt The Rat]

remember your arithmetics

9.8 * 4 = 9*4 + 0.8 * 4 = 36 + 3.2 = 39.2
etc

10 * 4 - 0.2 * 4 = 40 - 0.8  = 39.2

[fredrick]

do they accept answers left like 10g-20 or do we evaluate it?

[Mao]

98 - 20 = 78

I'd put both to be sure.

[fredrick]

Yeh lol can we still leave it like above.

Yeh lol can we still leave it like above.

i have a feeling no... unless they say leave it in the form of ag-b [10g-20] a = 10 , b= 20

in one of the trial exams MAV  2008 exam 1 they made u convert it to complete newtons. only coz it was 10g/2 - 15...



thats pretty easy yeah?
