Help with trigonometry question

Hi, i need help in this trignometry question and i don't quite understand how to solve it this question is dealing with the equation:

y-k sin or cos (x-h)

---- = -----------------

b a

just in case your not sure

k = vertical shift

b = amplitude

h = horizontal shift

a = period

here is the question:

a tire with a diameter of 63 cm coasts at 1.6 m/s over a nail at exactly 12:00 noon. the nail is stuck in the tire but does not deflate

a. how high above the ground will the nail be at:

1. 12:00:08

2. 12:00:15

3: 12:01:00

4: 12:15:00

b. Find the first four times the nail at 10 cm above the ground

thanks! i really need to understand this question
