True or False. While going at a constant speed, a 6 kg mass accumulates another 6 kg making it a total of 12 kg. The change in kinetic energy is zero.
Homework Answers
before accumulation the speed is v
after accumulation,since the mass is increasing so speed decreases and is less than v
So there will be certian change in kinetic energy ,since the KE =
0.5*m*v^2
hence the answer is false
