Object a, mass 4.24×105 kg , is at rest in reference frame a, and object b, mass 4.11×104 kg , moves at 0.875 c0 in the positive xdirection in this reference frame. a reference frame c moves at 0.200 c0 relative to reference frame a and moves in the same direction as object b.
a) what does an observer at rest in a measure for the momentum of b?
b) what does an observer at rest with respect to object b measure for the momentum of a?
c) what is the momentum of the object a as measured by an observer at rest in reference frame
d) what is the momentum of the object b as measured by an observer at rest in reference frame c?
