Answer:

v = -\frac{n \ m}{M} \ v'

for the man to return to the ship he must throw the balls in the opposite direction of the ship

Explanation:

For this exercise we can use the conservation of momentum. Let's form a system made up of man and baseballs.

Initial instant. Before throwing the balls

     p₀ = 0

Final moment. After throwing the balls

     p_{f} = M v + n m v '

where M is the mass of the man, m is the mass of each ball and n is the number of balls , v isthe speed man and v' is the speed ball

     

Since the forces are internal, the momentum of the system is conserved

     p₀ = p_{f}

      0 = M v + n m v ’

      v =- \frac{n \ m}{M} \ v'

If we analyze this expression, for the man to return to the ship he must throw the balls in the opposite direction of the ship
