A body is projected vertically upwards and moves so that s = ut – 16t2, where s is the distance (in metres), t is the time (in seconds), and u is the initial velocity of the body (in metres per seconds). Find the time taken for a body to rise 275 metres, if its initial velocity is 150m/s.
so u=150m/s s=275m t=our unknown variable so u just substitute into the equation and then solve the quadratic

but how do I solve for t when there is a t and a t 2

s is the distance from the ground to the projectile right

I'm not in it silly, quick reply
but it seems like into physics, intertia and gravitational acceleration and the like

oooo sweet!
let's write an equation about it.
coasters location at any given point can be given by
C=a(rt^2) Where C is coasters location, A is acceleration due to ketamine, r is resistance provided by solid or imaginary objects while K-holing, and t is time in seconds.
Solve for C if A = infinityyyyy

dood no way on k u dont fly that fast havnt u ever kholed u fly at such a perfect speed so that u can see the objects that u pass by and sometimes u can merge with objects that u fly into its so fucking wicked ive became trains, buildings, other ppl its the best experience ever

dude 3.75 was wrong
its just math 2 nothing specific
its a program and I have to give it the exact answer, 3.75 was incorrect

nah id say a=9.8m/s^2 and sometimes i hit that terminal velocity and i can even slow down the speed at which i fly ketamine is like 100x kewler than any hallucinogen because its like pure out of body experience

yeah I solved it a couple different ways. that was using the quadratic method that coasty suggested. I got 3.75 and 6.875.
what was the correct answer? somewhere around 1.9ish?

well it's a weird equation. I've never seen an equation dealing with an object flying straight up where the initial velocity and time in seconds are linked variables (the "ut" in that equation). It's kinda tough because it's completely illogical in terms of the equation you'd actually use to solve that. But I'm assuming if you use the correct one you'll get the "wrong" answer.
using factoring and solving for t I came up with 1.35s, does that work?
