<prompt> Ke matla afe a kinetic a ntho e boima ba 3kg le lebelo la 15ms?nan  <response>: Instruction in English: What is the kinetic energy of an object with a mass of 3kg and a speed of 15ms? . Response in English: The kinetic energy of an object can be calculated using the formula: KE 0.5 x m x v2, where KE is the kinetic energy, m is the mass, and v is the speed of the object. Plugging the given values into this formula, the kinetic energy of an object with a mass of 3kg and a speed of 15ms is 0.5 x 3kg x 15ms2, which equals 337.5 Joules. . Response in Sesotho: Matla a kinetic a ntho a ka baloa ho sebelisoa foromo: KE 0.5 xmxv2, moo KE e leng matla a kinetic, m ke boima, me v ke lebelo la ntho. Ho hokela litekanyetso tse fanoeng foromong ena, matla a kinetic a ntho e boima ba 3kg le lebelo la 15ms ke 0.5 x 3kg x 15ms2, e lekanang le 337.5 Joules.
