Which has the greater kinetic energy, an object with a mass of 3 kg moving with a velocity of 2 m/s or a?

second object with a mass 2 kg moving with a velocity of 3 m/s? Show all your work in details.Which has the greater kinetic energy, an object with a mass of 3 kg moving with a velocity of 2 m/s or a?
KE=1/2mv^2.


The 2 kg mass moving at 3m/s will have the greater KE.Which has the greater kinetic energy, an object with a mass of 3 kg moving with a velocity of 2 m/s or a?
Second object.


(1) 陆mv虏 = 陆 x 3 x 2虏 = 6 joules


(2) 陆mv虏 = 陆 x 2 x 3虏 = 9 joules
