Hey Mr Whibbley the links in the description dont work just letting you know

[asmc]

For 3a and 3b why do we equate the graph to the shm formula given that the graph labels are for linear acceleration and velocity instead of angular in the equation?

My physics exam is tomorrow, goodluck to me :(

[tree_stump]

for questions 3c could we use the y=Acoswt equation instead of the reference circle?

[mrkrabbes]

for question 3c, i thought phasors go anti clockwise, so shouldn't your diagram be mirrored on the right? thanks
