Cart on a Ramp – Motion Detector Sim

Speed

Lab scenarios (from handout)

Controls

Detector at:

Ramp angle θ: ° Start position (distance from detector): m Initial velocity (detector sign; ): m/s Rolling friction coefficient μ: Zero position offset (scenario 6): m from detector

At ends / min range (0.15 m):

Ramp length 2.0 m. Ramp tilt drawn 2× exaggerated for visibility. g = 9.8 m/s². a = ±g sinθ − sign(v)·μ g cosθ.

Graphs show what the detector reports: position = distance from detector − zero offset (+ = away from detector). Blue = measured; red = your prediction sketch.
