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

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
