Understanding Forces and Motion on Rough Ramps
Explore the impact of friction forces on blocks sliding at different speeds on rough ramps. Learn about the direction of friction forces and how they affect the motion of objects both sliding down and up the ramp. Additionally, discover how friction comes into play when a block is motionless on a rough ramp. Delve into concepts of constant speed, increasing speed, and spring behavior in various scenarios presented.

As shown in Figure A, a block of mass m is hanging from a spring attached to the ceiling. As shown in Figure B, two blocks of mass m/2 are hanging from two strings that are attached to a spring that has the same spring constant k. If the spring in Figure A is stretched a distance d, how far will the spring in Figure B stretch? A.
