n outer space, far from other objects, block 1
of mass 40 kg is at position
(7,9,0)
and block 2 of mass 1000 kg is at position
(17,13,0)
Since the z components of position are
zero, the (vector) gravitational force acting
on block 2 due to block 1 will be
(-21.359e-9,-8.54198e-9,0)
At 4.6 s after noon both blocks were at rest at
the positions given above. At 4.7 s after noon,
what is the (vector) momentum of block 2?
px,py,pz
