20,000 kg truck going 23 km/hr? At what speed does a 950 kg compact car have the same kinetic energy as a 20,000 kg truck going 23 km/hr?
I have no Idea how to do this, I tried to use the KE equations but am not getting the right answers.
please show me your steps, and attempt to answer some of...
If this transfer is only 25% efficient, what is the max. velocity that the 70 kg target can reach?
I took 35J and divided it by 70kg, but before looking at the answer, I had not idea what to do. What is the reasoning behind this? 35 kg(m^2/s^2)/ 70 kg= .51 m^2.s^2?????

I just got a kinetik battery and it's a hc-1400. when I test it with my multimeter it only shows 6 volts. I know that regular car batteries have 12V. can I use this battery on my car as a replacement? or not? and is there anything I need to know about changing the battery so that I dont mess...
