At time 9 s, a car with mass 1400 kg is lo
cated at <94m, 0 m, 30m> and has momentum
<4500 kg · m/sec, 0 kg · m/sec,−3000 kg · m/sec> .
The car’s momentum is not changing. At time
18 s, find the position of the car:
~d = <dx, dy, dz>

There were 18 kids at the play.Each kid had 4 dolls with them. How many dolls were there?
