i don't get

#

so i used suvat to find 96

#

but i don't understand why isn't 96 the final answer for b?

#

@ me please

#

@umbral yacht because you are looking for total time and 96 is just an intermediate value of calculations?

umbral yacht
#

what did it mean

#

like

#

also why does it say 15+9T when the x axis its 15+5T

umbral yacht
#

i see it

#

look at v, when you divide constant factor it left behind this intermediate number 96 which is basically part literal expression for one side's length, just follow where 480 was split up

umbral yacht
#

hmmmm

#

wdym divide constant factor

1/2 * 10 = 5

#

1/2 - trapezoid formula

umbral yacht
#

OOKKOK I see it

spark niche
#

10 is height/velocity

umbral yacht
#

thank you

umbral yacht
#

ooh

#

well, you answering your questions

umbral yacht
#

what

spark niche
#

take a look at formula

#

and what i've sent you

spark niche
umbral yacht
#

they are different right?

#

SUVAT: s = 1/2(u+v)t
Trapezoid Area: A=1/2(a + b)h

#

2x + 5 = 25

#

what

umbral yacht

umbral yacht
#

no

spark niche
#

you had like

#

[\frac{480}{5} = 9T + 15]

[96 = 9T + 15]

#

but why is 9T + 15 inside the brackets

#

like that's the time right

spark niche
#

no, but i see what you mean

umbral yacht
#

so should i just not use that equation and stick to using the area one

#

bc this is lowk confusing me

spark niche
#

(top base + bottom base) = 9T + 15

umbral yacht
#

yes yes okay
