What Would Be the De Broglie Wavelength For $1 - \mathrm { g }$

Short Answer

What would be the de Broglie wavelength for $1 - \mathrm { g }$ object moving at the earth's escape speed 25,000 mph (about $11 \mathrm {~km} / \mathrm { s } )$ ? $\left( h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)$
