Let's see
Momentum be P
On comaparing
- c=1
So
- b-3c=1
- b-3=1
- b=1+3
- b=4
and
- -a-b=-1
- -a-4=-1
- -a=-1+4=3
- a=-3
So the unit is
- DV⁴/F³
How are primary and secondary succession similar and how are they different?

If the current takes him downstream we must find the resultant vector of the velocities: 
Then if the river is 3000 m-wide the swimmer will have to pass:
1.3520747 · 300 = 4056.14 m t = 4056.14 m : 1 m/s
a ) It takes 4056.15 seconds ( 1 hour 7 minutes and 36 seconds ) to cross the river.
b ) 0.91 · 3000 = 2730 m
He will be 2730 m downstream.
