A 310-g air track cart is traveling at 1.25 m/s and a 270-g cart traveling in the opposite direction at 1.33 m/s. What is the speed of the center of mass of the two carts

The speed of the center of mass of the two carts is 0.049 m/s.

Explanation:

Given;

mass of the first cart, m₁ = 310 g = 0.31 kg

speed of the first cart, v₁ = 1.25 m/s

mass of the second cart, m₂ = 270 g = 0.27 kg

speed of the second cart, v₂ = - 1.33 m/s (in opposite direction)

The speed of the center of mass of the two carts is calculated as;

Therefore, the speed of the center of mass of the two carts is 0.049 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.
