a van a mass of 3000 kg and a car has a mass of 1500 kg. If both are traveling at the same speed, how would you compare their kinetic energy?

Sagot :

Kinetic Energy (KE)= [tex]\ \frac{1}{2} mv^{2} [/tex] where m is mass and v is velocity. since the velocity is constant and mass and KE are directly proportional, when mass is doubled, so does KE and stuff. now, your first mass is 1500 kg. the second one is twice the first, meaning the KE of the first will be doubled, too
