A 5kg baseball and a 10kg softball are thrown at 10 m/s. Which ball has more kinetic energy?
Answered by R_scott
k.e. is proportional to the mass of an object and the square of its velocity

the balls have the same velocity but one has twice the mass
Answered by skyler
u didn't answer the question which has more kinetic energy
Answered by oobleck
yes, he did.
twice the mass, so twice the KE
(2m)v^2 = 2*mv^2
