    Two unknowns in trigonometric calculation?

    Hah, nevermind, I found a way to find x and then I could just insert the value to get v, just like I thought! :biggrin:

    Two unknowns in trigonometric calculation?

    Homework Statement A boat leaves the harbor going 60 degrees north-east with the speed 20km/h. 3 hours later, another boat leaves a harbor 160km to the east with a speed of 70km/h. What course should the second boat have to meet the first? Homework Equations Not 100% sure what equations would...

    How Can Force and Time Determine Velocity in Physics Problems?

    Awesome, thanks a lot for all the help! I really appreciate it. :biggrin: Edit: Also, what's the connection/reason for using the F= m∆v/∆t formula/equation? Any way to connect it to any of the "basic" formulas for the things I mentioned earlier that we had talked about in class (kinetic and...

    How Can Force and Time Determine Velocity in Physics Problems?

    Let me see if I got this right (English isn't my primary language, nor the language in which my physics education is held, so I might've misunderstood some parts of this last post since I'm not too sure about how to solve this third question to begin with) F= \frac{m × ∆v}{∆t} \Leftrightarrow...

    How Can Force and Time Determine Velocity in Physics Problems?

    Thanks. And yes, my arguments for why these things are happening on #2 are pretty vague. Thanks for the help, really appreciate it. I assume this would be caused because of the scale having to push the man upward with a higher force to stop his fall, as opposed to simply holding him in...

    How Can Force and Time Determine Velocity in Physics Problems?

    Homework Statement The graph below shows the force as a function of time when a man jumps on a bathroom scale. 1) Determine the mans weight (mass, kg) using the graph. 2) Describe what happens in the time intervals A, B, C and D. 3) Determine the velocity of the man as he leaves the scale...
