I think they're different component of x and y and thus you can't use them without linking time

Briliant Vissh. Answer seems consistent with fellow class mates. You're an absolute legend

Nah I think there was a mistake. Can Someone confirm with me that t=~1.903

I got t= 3.18 Is that right. Maybe I screwed up somewhere along the line. I'll double check in the morning as I am in Australia and it's getting late

So is the time not 3.2 since I assumed Uy was 10m/s? Wouldn't I need to know U to be able to find Uy then. And Ux would be range over time. But how would you find time without finding Uy Could you make Vy=0 and use the equation Vy^2 = Uy^2 + 2a (delta) Y

Where would range play a part in the question? Doesn't range (delta)x only matter on horizontal motion? I mean if you can find time the you can find Ux but I didn't know you needed to use it to find time

Thank you Drelt

You can also use orbital velocity and work it out from there.

110% mass of the sun.

Use Keplers law of period and the mass turns out to be 2.207610x1030

Homework Statement A projectile is fired from the top of a 10m high cliff. It has a range of 152m and reaches a maximum height of 8.2m above the cliff top. Determine the time of flight Is Delta Y =18.2? Is Uy=10 Homework Equations Delta Y = Uyt + 0.5 ayt The Attempt at a Solution...

Thanks so much tiny-tim, You're a absolute legend

It's not that i Don't like it, I was just curious to an extent. But when you rearrange it, why is it the one with t^2 the one that's represented as 'a' and the one with 't' alone represented as b in the equation for the quadratic formula. I know it is but why. I know nothing about maths or physics.

Ohh early start I would gather. Anyways, is the quadratic formula the only way it can be done?

Would I have to use the quadratic formula to solve it?
