Answer:
142m/s2
Explanation:
The solution is in the attached file below
Some of the energy is converted into heat. This is the main reason why electrical material gets hot when connected to a source. Therefore, your initial energy does not equal final energy. This does not violated energy conservation law because the energy is being converted so it is never lost.
Friction causes kinetic energy to be converted into 'thermal energy'. The answer to this question is 'thermal energy'. An example would be if something is being rubbed against another object, there is friction and thermal energy will be produced. I hope this helps you on your assignment! You're welcome.
An object with a greater mass will have more inertia as it takes more force to change their motion.
