Question

d=ut+0.5at²
how do I solve for a?

Answer 1

So subtract ut from both sides first.

Answer 2

ok so I would take the 0.5at² and subtract ut from it. so my answer would be just the 0.5at²??

Answer 3

Yes.. on the right side though.

Answer 4

ok

Answer 5

How to isolate a?

Answer 6

yea. I cant figure out how to do it though. I got four other problems I got to do lik this and im stuck on how to figure it out.

Answer 7

From where I stopped a can be isolated by dividing both sides by 0.5t²

Answer 8

yea. That's as far as I can get. but how is that the answer to a?

Answer 9

thank you.! (:

Answer 14

haha yea (: thanks for helping though

Answer 15

ok so this equation is d=0.5gt². d=490ft. and t=10sec. so the equation would be 490ft=0.5g(10sec)² right.?

Answer 16

Yes.

Answer 17

ok so would I then have to take 10x10 or would I have to multiply 10x0.5g?

Answer 18

10 squared is 100.

Answer 19

So 100*0.5g

Answer 20

ok and then the answer to that is 50.0 so it would be 490ft.=50g

Answer 21

and then I would have to divide both sides by 50 and the answer would be g=9.8

Answer 22

Yes.

Answer 23

ok. thanks for helping :)
