Work is the change in kinetic energy. Work = force x distance. So the work for both blocks is the same (1/2)

Intuitively, the same force on the same distance should lead to the same energy… I might be wrong, I didn't verify

frictionless 2M. friction it may involve acceleration points like at some point it reaches max acceleration just my thoughts

(1/2)M2. Since they're absorbing energy at the same rate M2 will accelerate at a slower rate. Thus, it'll take longer to achieve the distance. Thus, it'd have absorbed energy for longer.

There is no such thing as friction less.

acceleration is half for the 2m. therefore final velocity is 1/1.414 for the 2m. therefore kinetic is the same for both blocks.

Conservation of energy. Where else can the energy go except into k.e. So they must be the same.

Hmm… first guess was same energy because B has more mass and therefore accelerates half. But its like free fall. So B should have more energy. Unsure

The kenetic energy in the block is eqyal to the work done by thevforce. Work does not depend on mass. The kineticis the same because the work is the

Kinetic energy is force over time not force over distance. So the one with more mass which accelerates slower for more time ends with more energy.

So no time, that gives it away.

Same (as usual :)

Because the force was applied during the same distance, the kinetic energy will be higher on the higher mass.

Fitch Gamer :
If you crunch the numbers then it comes out to equal energy so it confirms that the same force over the same distance is the same energy

If the force was applied for equal time, kinetic energy would be the same. Here m2 is heavyer, so it will take longer time to go 1 meter. Hence more energy will be given to m2.
