A0.180-kilogram cart traveling at 0.80 meter per second to the right collides with a 0.100-kilogram cart initially at rest. the carts lock together upon collision. calculate the final velocity of the carts.

According to the saving of the momentum law, the total momentum before collision equals to the total momentum after collision

After collection, the 2 carts lock together, one body with a mass and velocity

from the definition of the momentum

thus

we calculate the velocity

the answer is a. hope this .

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.
