On a smooth surface, a 0.140-kg toy car 1 at the velocity of 5.0 m/s collides elastically with another 0.100-kg toy car 2 with a velocity of 3.0 m/s. The
velocities of the two toy cars are in the same direction. After the collision, toy
cars 1 and 2 keep moving in the same direction with toy car 1 having a velocity of
2.8 m/s. What is the velocity of toy car 2 after the collision? Show the steps on
how you arrived at your final answer. Are the momentum and kinetic energy of
the system conserved in this collision? Explain.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

dang that balls went far

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.
