After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +1.5 m/s. Miranda runs after her at a velocity of +4.2 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashley's mass is 48 kg, and Miranda's is 77 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow.

3.16m/s

Explanation:

Mass of Ashley = 48 kg

Mass of Miranda = 77 kg

u1 = 1.5 m/s

u2 = 4.2 m/s

m1u1 + m2u2 = (m1 + m2)v

v = m1u1 + m2u2 / m1 + m2

So v = (48x1.5 + 77x4.2) / (48+77)

= 3.1632

= 3.16m/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.
