    How Can You Show That Two Ships Will Collide Using Vectors?

    I came across this question in a past paper, and am absolutely stuck. A coastguard station 0 monitors the movements of ships in a channel. At noon, the station's radar records two ships moving with constant speed. Ship A is at the point with position vector (-5i + 10j) km relative to 0 and...

    How Do You Calculate Distance in a Two-Stage Lift Journey Using SUVAT Equations?

    Thank you. I'm sorry, but I'm not feeling particularly intelligent today, or perhaps I've just called it something different, but could you explain the above formula? Thank you ever so much!

    How Do You Calculate Distance in a Two-Stage Lift Journey Using SUVAT Equations?

    I have a mechanics exam coming up, and I'm going through a textbook answering questions. I'm really stuck on the following: A lift ascends from rest with an accceleration of 0.5ms before slowing with an acceleration of -0.75ms for the next stop. If the total journey time is 10 secs, what is...
