It is called "distance". In fact, distance measures how far apart two points are from each other, and it is always a positive number.
In mathematics, for instance, the distance between two points of coordinates (x1,y1) and (x2,y2) on a xy-plane is defined as

and by definition, this number is always positive.
Momentum is mass times velocity. So here we can just substitute in our givens and solve for velocity.
.600kg*m/s/.350kg=1.71m/s
Hope this helps! Thank you!
Answer:
F=523712 N
Explanation:
density=mass/volume
and shape is cubic so
volume=(4)^3
volume=64 m^3
mass=835*64
mass=53440 Kg
Hydrostatic force=53440*9.8=523712 N
" 50 W " means " 50 Watts " or " 50 Joules per second ".
(500,002 J) / (50 J/sec) = <em>10,000.04 seconds</em>
(That's 2 hours 46 minutes 40.04 seconds.)
