MauryanBroski yeah ur right, bc happy and grumpy and alternate between each two seats bc it doesn't matter if grumpy is left or right of happy, and there are 6 of these combinations, so 6x2 is right, then of course the factorial of 5 is 120 so times them and 1440. Good job, also sui this is also an explanation for u. I do have one question though, i am rlly bad at these questions: how many different numbers from 4,5,6,7,8,9 can be made so that they are larger than 6000 and there is no repetition of numbers?

      :): hope it stays like this bc i actually want a chat without NHS bc he just makes things hostile for no reason

          Hey guys, can I have help with kinematics?

            Matto120 whats that 😭😭 also do we have to learn surds and trig and other stuff bc a lot of ppl that did the test last yr are saying that there was a lot of trig but ive done sm practice tests and there hasnt been a bit of trig theres been a lot of linear and simultaneous equations

                anusha its like the velocity two objex=cts move at eachother or smth im still doing it lol

                    Is anyone able to finish their N.R paper on time?

                    anusha ill mater it tommorow and js explain it, but basically in a word problem they will give the info js subtitute into the 4 formulas and get ur aswer for the other value. Memorise and revise, watch tutourials and gl for prep

                        anusha Kinematics is the study of motion, without any reference to the forces that cause the motion. It basically means studying how things are moving, not why they're moving. It includes concepts such as distance or displacement, speed or velocity, and acceleration, and it looks at how those values vary over time.

                          There are four basic kinematics equations:
                          v = v 0 + a t.
                          Δ x = ( v + v 0 2 ) t.
                          Δ x = v 0 t + 1 2 a t 2.
                          v 2 = v o 2 + 2 a Δ x.

                          For example, if it is given that a car is travelling and it accelerates from its resting position with an acceleration of 6.5 m/s2 for a time span of 8 seconds, reaching a final velocity of 42 m/s, east and a displacement of 120 m, then the motion of this car is fully described. Now, if anyone of this information was not provided, we could have easily calculated it with the help of kinematics equations

                          • :): replied to this.

                            ok ok sorry to everyone for the roasts
                            hope u all get in to your dream schools
