A 1 g object traveling at 10 m/s collides with a stationary 100 g object at rest and bounces back at the same speed. Assuming conservation of momentum, what is the speed of the 100 g object after the collision?​

m vi = initial momentum

m vf + M V  = final momentum

M V = m (vi - vf)      combining equations

V = m / M (vi - vf)

Let vf = 10 m/s and  vi = -10 m/s

Then V = 1/100 * (-20 m/s) = -.2 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.
