Question

Find a model for simple harmonic motion if the position at t = 0 is 0, the amplitude is 5 centimeters, and the period is 2 seconds.
which is the answer d=5sin(pi t) or d=5cos(pi t)

Answer 1

you want zero when you replace t by 0, so sine is the best candidate for that

Answer 2

i think its 5sin(pit) is that right?

Answer 3

if you replace t by 0 in the second one you will get 5
yes sine, not cosine

Answer 4

ty

Answer 5
