4. A system that exhibit harmonic motion oscillates between a height of 6 ft. and - 3 ft. At time = 0 the system is at its minimum height. At time = 2.5 seconds it's at the maximum height. Sketch a graph of the system and write a sinusoidal
equation that models this harmonic motion.
1. Amplitude (a)
ft. (Round to nearest tenth)
2. Vertical shift (d) =
ft. (Round to nearest tenth)
3. Period (P) =
sec.
4. Frequency (S) =___cycles/sec (Write as a fraction)
5. w =rads/sec (Write as a fraction. Use pi for 7)
6. h(t) =__cos(t) +
7. h(1.25) = __ ft. (Round to the nearest tenth)
8. h(3.75) =
ft. (Round to the nearest tenth)
