The closest is the one we're in. We call it the Milky Way galaxy.
The nearest one outside of the Milky Way is the Andromeda galaxy ... less than a piffling 3 million light years away, practically in our back yard.

A river flows due east at 1.50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant v
monitta

Answer:

a

   u =  10.11 \  m/s

b

   x = 44.996 \  m    

Explanation:

From the question we are told that    

        The velocity of the river due east is  v =  1.150i  \ m /s

        The velocity of the boat due north is  v_1 = 10j  \ m/ s

         The width of the river is  d =  300 \  m

Generally the velocity of the boat relative to the shore

           u =  \sqrt{v^2 + v_1^2}

=>        u =  \sqrt{1.50 ^2 + 10^2}

=>        u =  10.11 \  m/s

Generally direction of the boat relative to the shore is mathematically represented as

           tan \theta  =  \frac{v}{v_1}

=>        \theta  = tan^{-1}[ \frac{v}{v_1}]

=>        \theta  = tan^{-1}[ \frac{1.5}{10}]

=>        \theta  = 8.53^o

Generally the distance covered by the boat in the direction of flow of the river before reaching the north shore is mathematically represented as

             x =  d*  tan(\theta )

=>          x =  300 *  tan(8.53)

=>         x = 44.996 \  m

6. A 0.09 kg arrow hits a target at 22 m/s and penetrates 4 cm before stopping.
tatyana61 [14]
A ) v = v o - a t
0 = 22 - a · t
a · t = 22
d = v o · t - a t²/2
0.04 = 22 t - 22 t / 2
0.04 = 11 t
t = 0.04 : 11 = 0.003636 s
a = 22 / t
a = 6050 m/s²
F = m · a = 0.09 kg · 6050 m/s²
F ( target→arrow) = - 544.5 N
b ) F ( arrow→target ) = 544.5 N
c )  If the speed was doubled:  v = 44 m/s;
F = a m
a = 6050 m/s²
a · t = 44
t = 6050 : 0.04
t = 0.007272 s
d = 44 t - 44 t/2 = 22 t
d = 22 · 0.007272
d = 0.16 m = 16 cm
