Answer 1

A or B

Answer 2

not sure

Answer 3

im not sure either ..

Answer 4

asin(wt+k) would have been the answer but not on the list

Answer 5

can you recheck the brackets on C

Answer 6

This is the actual question

Answer 7

graph each and see which one looks most like the harmonic motion

Answer 8

B

Answer 9
