The volume of water in a dam is determined by the formula V = 27h² (3d-3h). After a rainfall, water is flowing into the dam resulting in an increase in the water level h at a rate of 0.06m/hr while the diameter d of the dam is increasing at a rate of 0.25m/hr. Determine the rate at which the volume is changing the instant when d = 20m and h = 6m. Use the Maclaurin series to expand te to four non-zero terms.

Terhyon throws throws a football to Javon. The throw lasts for 4 seconds and reaches a maximum velocity of 40m/s. Calculate the acceleration of the football.
