$\longrightarrow$ $\large\mathrm\purple{\boxed{The\ statement\ is\ false}}$

$\huge\mathrm\star\red{\boxed{Reason:-}}\star$

$\longrightarrow$ $\mathrm\purple{This\ is\ because\ the\ minimum\ velocity\ with\ which\ the\ spacecraft\ must\ be\ projected\ so\ that\ it\ escapes\ the\ Earth's\ gravitational\ pull}$

$\longrightarrow$ $\mathrm\purple{So,\ the\ initial\ velocity\ of\ the\ spacecraft\ must\ be\ greater\ than\ or\ equal\ to\ escape\ velocity\ of\ Earth.}$

$\Large\mathrm\star\purple{\boxed{What\ is\ escape\ velocity}}\star$

$\longrightarrow$ $\mathrm\purple{Escape\ velocity\ is\ the\ minimum\ velocity\ required\ by\ a\ body\ to\ be\ projected\ to\ overcome\ the\ gravitational\ pull\ of\ the\ earth.}$

$\longrightarrow$ $\mathrm\purple{Initial\ velocity\ is\ a\ velocity\ in\ which\ the\ body\ starts\ moving\ to\ a\ reference\ point}$
