At 1.00 PM, Mary ( on a rocket moving past the earth) records anearth-bound stationary observer as having length L1. At 2.00 PM ,Mary (still on the rocket ) notes this observer to have length L 2< L1. At 2.PM,this earth-bound observer "sees" the mass of therocket to be ( ) than it seemed to be at 1.00 PM?

(A) greater
(b) less
(c) the same
(d) more information is needed
