:a 10 g bullet travelling at 300 m/s hits a 500 g wooden block that is initially stationary. the bullet becomes embedded in the block, and both travel together along a frictioneless surface. answer each of the following questions a) what is the kinetic energy of the bullet before it hits the block? b) what is the velocity of the bullet+block after the collision?

450 J

5.88235 m/s

Explanation:

The kinetic energy is given by

The kinetic energy of the bullet before it hits the block is 450 J

= Mass of bullet = 0.01 kg

= Mass of block = 0.5 kg

= Initial Velocity of bullet = 300 m/s

= Initial Velocity of second block = 0 m/s

v = Velocity of combined mass

In this system the linear momentum is conserved

The velocity of the bullet+block after the collision is 5.88235 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.
