Achild in a boat throws a 5.80kg package out horizontally
with a speed of 10.0 m/s, fig. 7-31.calculate the velocity of the
boat immediately after, assuming itwas initially at rest. the mass
of the child is 29.0 kg and that of the boat is 50.0 kg. ignore
water resistance. find itsmagnitude.

0.734 m/s

Explanation:

Since there's no external force outside the system, by the law of momentum conservation, momentum before the throw (which is 0) must be the same as after the throw:

where m_p = 5.8 kg is the mass of the package

           v_p = 10m/s is the velocity of the package

           m_c = 29 kg is the mass of the child

           m_b = 50 kg is the mass of the boat

As the package and the boat has opposite directions of motion, they should have opposite velocity:

So the magnitude of the boat velocity is 0.734 m/s

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
