de Broglie wavelength of the electron and ball

Part 1) Through what potential difference would an electron have to be accelerated from rest to give it a de Broglie wavelength of 1.2 × 10^ -10 m?
The mass of an electron is 9.109 × 10^-31 kg and Planck's constant is 6.626 × 10 ^-34 J s
Answer in Volts.

Part 2) A ball has a mass of 0.303 kg just before it strikes the Earth after being dropped from a building 78.7 m tall. The acceleration of gravity is 9.8 m/s^2 .
What is its de Broglie wavelength?
Answer in units of m.
