You are once again on the Pizza Planet of Alpha Centauri IV where the acceleration due to gravity is still gP = 9.12 m/s2 . Luigi is on one of the long, straight, moving walkways which has a constant velocity of 12.5 m/s, but he is late for an important engagement with Mario so is walking at a constant velocity of 5.50 m/s with respect to the moving walkway. You observe Luigi from an adjacent walkway that is moving at a constant velocity of 12.5m/s in the opposite direction. At some instant t = 0, the ever-vigilant Luigi tosses a clump of dough upward in the air and catches it at the same vertical location but 34.0 m farther away with respect to the stationary ground.
In the frame of reference of Luigi’s walkway:
(a) At what angle to the vertical does Luigi throw the dough?
(b) What is the initial velocity of the dough relative to Luigi’s walkway?
(c) What is the shape of the dough’s trajectory relative to Luigi??
From the reference frame of your moving walkway:
(a) What is the shape of the dough’s trajectory?
(b) With what initial velocity does Luigi throw the dough?
