Question

Need help really hard

Answer 1

The distance traveled by a marble on a flat table as it rolls in a straight line is determined by the formula:
S=ut + 1/2at^2 ,
where
s = Distance traveled u = Initial Velocity
t = Time elapsed
a = Acceleration
Which of the following shows the distance traveled formula solved for a?
A. a= 2s-2ut/t^2
B. a= 2s-ut/t^2
C. a= 2s-2u/t
D. a= s-ut/t^2

Answer 2

really hard? xD

Answer 3

\(\large \bf s=ut+\frac{1}{2}at^2\) solve for "a" then

Answer 4

tis just a simple linear equation

Answer 5

I need help still @jdoe0001

Answer 6

have you covered linear equation simplifications yet?

Answer 7

No @jdoe0001 help

Answer 8

s = ut + 1/2at^2
To solve for 'a', isolate 'a':
subtract ut from both sides. What do you get?

Answer 9

@eki1709
I suggest you recheck the answer choices. You need to insert parentheses on the numerators whenever you deal with fractions. If we evaluate the answers according to the BEDMAS rules, none of the choices is correct.
For example, choice A should have been written
A. a=(2s-2ut)/t^2
if the original (printed) answer choice was written
\(\large {A. a=\frac{2s-2ut}{t^2}}\)

Answer 10

i think he means pemdas rules
