Astudent performed a scientific investigation using four small balls of the same size and shape and a ramp. each ball was taken to the top of the ramp and released. after several trials, three of the balls rolled across the floor and went about the same distance each time. the striped ball only went about half the distance as the other balls. which of the following is a likely explanation that fits the evidence from the experiment?
all four balls are made of the same of material.
the striped ball is not made of the same material as any of the other balls.
the student made a mistake and did not release the striped ball from the same spot.
the ramp is uneven, so the striped ball did not roll down it in the same manner as the other balls.
