rest when two swimmers dive off opposite ends simultaneously, each with a horizontal velocity of 3,0 m.s^-1 relative to the water.
With what velocity and in which direction will the boat start to move immediately after the swimmers have dived off?
With what velocity and in which direction will the boat start to move immediately after the swimmers have dived off?

Use conservation of momentum considering a system of the two men and boat.
Let the right hand side, x direction, be positive, then:
Initial net momentum before jumping = final net momentum after jumping.
Initially, assuming th boat is at rest (the question doesn't say) momentum is zero. Add the sum of m*v for each respective object and solve for the unknown variable v for the boat.
