Question

RELATIVE MOTION Name Mech HW-27 The relationship Explain how this relation is consistent with your result above for the displacements. c. onea ruck t nck pow is known as the Galilean transformation of velocities. =- Does this relationship apply to the instantaneous velocities at instant 2? at instant 37 Explain. r P moves to the west with constant speed v, along a straight road. Car Q starts from rest at tant 1, and moves to the west with increasing speed. At instant 5, car Q has speed w,relative he road (w0 < vo). Instants 1-5 are separated by equal time intervals.

Answer 1

c) V_car, cone = V_car, turck + V_truck, cone implies integral V_car, cone dt = integral V_car, truck dt + V_truck, cone dt implies d_car, cone = d_car, truck + d_truck, cone [d represents displacement] It applies at all instantaneous values.
