2) A classical cartoon situation: Lobster, with mass m, on one edge of a carpet with length Land mass M is suddenly starting to run at maximum speed Vmax along the carpet. Because there is negligible friction between the carpet and the floor, the carpet slides out underneath Lobster, and so it doesn't quite move as much as it wished. a. Make a detailed schematic drawing of the situation. b. How long until Lobster reaches the end of the carpet? c. Watching it from a steady frame of reference, how fast and in which directions are the carpet and Lobster moving, respectively? d. How far did Lobster progress in that steady frame of reference when it reaches the end of the carpet? e. Ifm = 1 kg, M = 3 kg, L = 20 m, Vmax = 0.25 m/s, how long until Lobster reaches the end of the carpet, and how far has it moved in the steady frame of reference? How far has it moved on the carpet?

Transcribed Image Text:2) A classical cartoon situation: Lobster, with mass m, on one edge of a carpet with length L and
mass M is suddenly starting to run at maximum speed Vmax along the carpet. Because there is
negligible friction between the carpet and the floor, the carpet slides out underneath Lobster,
and so it doesn't quite move as much as it wished.
a. Make a detailed schematic drawing of the situation.
b. How long until Lobster reaches the end of the carpet?
c. Watching it from a steady frame of reference, how fast and in which directions are the
carpet and Lobster moving, respectively?
d.
How far did Lobster progress in that steady frame of reference when it reaches the end of
the carpet?
e. If m = 1 kg, M = 3 kg, L = 20 m, Vmax = 0.25 m/s, how long until Lobster reaches the end of
the carpet, and how far has it moved in the steady frame of reference? How far has it
moved on the carpet?

Introduction:
Disclaimer: “Since you have asked posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get remaining sub-part solved please repost the complete question and mention the sub parts to be solved.”
All motion is defined in relative term. We define a frame of reference and define motion accordingly. We first draw the diagram of situation. We then find the time taken to reach the end. We then study the motion as from rest frame of reference.
