Question

The distance traveled by an object can be modeled by the equation d = ut + 0.5at2 where d = distance, u = initial velocity, t = time, and a = acceleration. Solve this formula for a. Show all steps in your work. plz someone >~<

campbell_st · Answer

steps

1. subtract ut from both sides of the equation

2. multiply both sides of the equation by 2

3. divide both sides of the equation by t^2

anonymous · Answer

how would it look like? ><  so d-ut=0.5at2 ? then ? d-ut2=0.5at?

campbell_st · Answer

the 1st step is correct

but put it in brackets before multiplying by 2....

anonymous · Answer

d-ut(2)=0.5at?  then d-ut(2)/t=A?

campbell_st · Answer

ok... 1st step correct

$$d - ut = 0.5 at^2$$

use brackets and multiply by 2

$$2(d - ut) = at^2$$

anonymous · Answer

oh ;-; so 2d-2ut=at2??

campbell_st · Answer

yes... but keep it written in brackets with 2 outside... 

now divide by t^2

anonymous · Answer

2(d-ut)=at2    2(d-ut)/t^2=A? ;-;

campbell_st · Answer

thats correct, well done

anonymous · Answer

wow thank you so much! !! im so happy ^_^

@hartnn can you explain what the answer Is I don't fully understand
