An object moves in a circular motion that is not uniform. The c$$rclude it describes has a radius of$12$meters. The speed of the object is$$given by$\mathrm{in}=3\mathrm{.}6+1\mathrm{.}5\mathrm{????}2$with$\mathrm{in}$in meters per second and$\mathrm{????}$in seconds. Determine the magnitude of its acceleration$$n $(\frac{\mathrm{????}}{\mathrm{????}2})$in$\mathrm{????}=3\mathrm{.}0\mathrm{????}.$
