Question

A student uses a spring scale to exert a horizontal force on a block, pulling the block over a smooth floor. the student repeats the procedure several times, each time pulling the block from rest through a distance of 1.0m. For which of the following graphs of force as a function of distance will the block be moving the fastest at the end of 1.0m.​

Answer 1

... I would need to see the graphs, but if it helps, the material the block is made out of can cause the block to move slower or faster. Say a sandpaper block and a smooth wooden block were pulled at the same time, the sandpaper block would move slower than the wooden block because there would be more friction between the floor and sandpaper than the floor and a wooden block. Hope this helps!
