\nThe correct option is A. The kinetic energy (KE) of an object is given by the formula $\\text{KE} = \\frac{1}{2}mv^2$, where $m$ is the mass and $v$ is the speed. Given $\\text{KE} = 100 \\, \\text{J}$ and $m = 2000 \\, \\text{g} = 2 \\, \\text{kg}$, we can solve for $v$.
\n<\/section>\n
\nSubstitute the given values into the kinetic energy formula: $100 \\, \\text{J} = \\frac{1}{2} \\times (2 \\, \\text{kg}) \\times v^2$. This simplifies to $100 = 1 \\times v^2$, so $v^2 = 100$. Taking the square root of both sides gives $v = 10 \\, \\text{m\/s}$ (since speed is a magnitude and must be non-negative).
\n<\/section>\n
\nIt is important to ensure that all units are in the standard SI system before calculation. Mass is given in grams and must be converted to kilograms (1 kg = 1000 g). Energy is given in Joules, which is the standard SI unit.
