An object with a greater mass will have more inertia as it takes more force to change their motion.
So, 50kg. (answer)
Answer:
If this helps, to work out the kinetic energy the formula is K (stands for kinetic energy) = 1/2 (half of) mass and velocity. So the answer is 450 joules.
Explanation:
In the object that has, the least inertia.
The particles in a solid are tightly packed and the particles do not move
The particles of liquid is less tightly packed and move with lesser kinetic energy than solids
The particles of gases are least tightly packed and the particles move around freely with the least kinetic energy than solids and liquids
