In physics, kinetic energy is the energy of an object in motion. kinetic energy, kkk, measured in joules (\text{j})( j, ), is calculated using the formula k =\dfrac{1}{2}mv^2k= 2 1 mv 2 k, equals, start fraction, 1, divided by, 2, end fraction, m, v, start superscript, 2, end superscript, where mmm is the mass of the object, measured in kilograms (\text{kg})( k, g, ), and vvv is the velocity of the object, measured in meters per second (\text{m}/\text{s})(m/ m, slash, s, ). rearrange the formula to solve for mass (m)( m, ). m=m=m, equals what is the mass of an object with a kinetic energy of 200{,}000\text{ j}200,000 j200, comma, 000, space, j and a velocity of 40 \text{ m}/\text{s}40 m/s40, space, m, slash, s? round your answer, if necessary, to the nearest hundredth. m=m=m, equals \text{kg}kgk, g
