Goal: Reasoning with dynamics
block of mass m, when placed on a rough inclined plane and moved, moves
down the plane with constant speed. If a block of mass 2m were placed
on the same incline and moved, it would …
- return to rest.
- accelerate until the speed is half.
- move with some constant speed.
- None of the above.
- Cannot be determined
The block will have the same motion. Both the gravitational force
and the friction force scale with the mass so there is no net force in
