Need help ASAP please

Consider a quantum mechanical world that has Schrodinger cat (mass = 1 ng), being chased by Schrodinger's dog (mass = 6.6 ng). The cat runs at a speed of 30 * 0.105 nm/swhile the dog runs at a ........... speed of 10 + 0.02 nm/s. Calculate a. the wavelength of the dog b. the uncertainty in the position of the cat
