Hi,

I'm new member and I would like to ask 2 questions:

1) Explain why an object too far from the motion detector will produce an incorrect distance reading?

2) Explain why we only consider one-dimesional motion when using a single motion detetor. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid an object into the beam from the side.
