## Homework Statement

haha, so hopefully my last question for the night!

Find the initial velocity, when the object is shot at 70 degrees and took 6.5s to land. (hint: look at the y direction first this time)

(For more information regarding my question, visit my earlier question from tonight: https://www.physicsforums.com/showthread.php?p=2890328#post2890328)

## Homework Equations

So, I doubt it will work, but there is the equation I used earlier, Range = v02sin2θ/g

## The Attempt at a Solution

Now, I know that there is the method of dividing it up into components of x and y, however I did not quite understand that. When calculating the initial velocity, given distance traveled and degree, I used Range = v02sin2θ/g which worked great (refer to https://www.physicsforums.com/showthr...28#post2890328 ), however, I don't know if that can apply to this too... Sorry, but physics is really confusing me at the minute

Let me try the component method... Okay, so, looking at the y component. Y is affected by g. V

_{oy}=s*Cos(theta)*t -.5gt^2. (I don't know if that equation is correct). So, than, I don't know s... stuck... Sure I did something wrong or I am just not getting something...
