Uncertainty problem

Chemistry Level pending

Suppose that the photons of a red light with $\lambda = 6.9 \times 10^{-7}$ m are used to move the position of a $0.145$ kg baseball exactly by one wavelength of the red light. What is the minimum spread in the speed of the baseball?

1.7 \times 10^{-28}\text{ m/s}

5.2 \times 10^{-28}\text{ m/s}

6.8 \times 10^{-28}\text{ m/s}

5.4 \times 10^{-27}\text{ m/s}
