[delicate sail]

Use s=ut+1/2at^2 and forget about that value for t

It’s just helping you go in the right direction

[near copper]

What value do I use for u though

[delicate sail]

So s=6.6m

u=17.5

[near copper]

oh alright

thanks will give it a try

[delicate sail]

You’ll get two values for t and both should be positive

Take the smaller away from the bigger value

And it should be less than 3 4/7

[near copper]

Did something wrong

[delicate sail]

Did you write it in the answer line?

[near copper]

Meaning?

I wrote 3.1

asks for ans in 2sf

[delicate sail]

Yeah I was just checking

[near copper]

I searched the question online and the solution is this

not sure where 6.6 is coming from

[delicate sail]

It’s the height

I’m so silly I missed that in your working I’m so sorry

You’ve multiplied it together, it’s a mixed fraction

[near copper]

isnt this 6/1 * 3/5 ?

= 18/5
= 3.6

[delicate sail]

No it’s 6 and then 3/5

It’s not multiplied

[near copper]

bruh im an idiot arent I

i couldve sworn my whole life ive multiplied

[delicate sail]

I missed it also

[near copper]

ohhhh

(((5 * 6) + 3) / 5)

= 33/5
= 6.6
