Bill forgets to put his car in park and it starts rolling west. when it is moving at a speed of 3.5 m/s, it collides with tanya's car, which is moving at a speed of 2m/s east. bill's car bounces backward (to the east) at a speed of 2 m/s. bill's car has a mass of 900 kg, and tanya's car has a mass of 1100 kg.

a. what is the total momentum of the system before collision?

b. what is the total momentum of the system after the collision?

c, what is the velocity of tanya's car after the collision?

PART A)

momentum of Bill's car

mass = 900 kg

speed = 3.5 m/s towards west

so momentum of this car given as

Similarly momentum of Tanya's car

mass = 1100 kg

speed = 2 m/s towards East

so momentum will be

Total momentum of both cars will be

Towards west

PART B)

Since there is no external force on the system of two cars

So here total momentum of both cars will remains conserved

So final momentum of two cars will be same as initial momentum

towards west

Part C)

final momentum of Bills car

Towards East

now we have

towards west

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.
