said a=4 since v=8 when x=0 and n=2 for memory. but then again couldve stuffed it
I got a = 5, since the centre of motion is x = 3. What I did was integrate the acceleration function and evaluated the constant using the condition x = 0, v = 8. I got:



I then set RHS = 0, and got after dividing through:
in which I said the particle oscillates within the range .

That aside though, god this exam was aids. Never have I hated taking a math exam more in my life. The 2020 kids were playing recruit mode. Truly fearful for Extension 1.
