Forever Lost

Chapter1

I woke up to the sound of my beeping alarm clock. It was 7:00am Monday September 8th. The first day of school. I got up and went to my bathroom pulling a comb threw my hair. I quickly applied some eye liner and went down stairs. I grabbed the first thing I saw. Pop Tarts. I threw them in the toaster and went back up stairs to get ready. When I came back down everyone was up. My mom was making her morning coffee and my sister Alice was eating cereal. I grabbed my (now cold) Pop Tarts and sat down.

Ever since the loss of my father last year, morning meals, or any meals for that matter where awkward. My dad knew how to make an entrance. His loud meal conversations about work as a lower and his life lessons filled up all the time we had to talk while eating. My father died in a car crash on Lake-a-way bridge. There was a collision with a transport truck. My dads car ended up in the ocean below the bridge. His car and all belongings were found, but his body wasn’t. Ever since the lost our family has been trying to move on. My sister is still coping and my mom says she’s moved on. For him, though me and my sister know she hasn’t.

When I was done my breakfast I brushed my teeth, grabbed my bag, and went to school.
Lake View Heights is a twenty minute drive. I have a rusty old black truck. That doesn’t have air conditioning, a lock that works, or a radio. Talk about a boring car ride.
I parked my car on the east wall. I grabbed my bag and my book and headed inside.

Baseball.
Ocean liner.
Both the same.
Can't say without more information.





2 . A truck moves with a certain momentum. If both its speed and its mass are doubled, how much greater is its momentum? [Hint]
Two times.
Four times.
Eight times.
Unchanged, the same.





3 . If a fast-moving object strikes you, you'll experience less force of impact if you can [Hint]
shorten the time the momentum decreases.
increase the time the momentum decreases.
either shorten or increase the time, for the result is the same.

The impulse will be more.
The impulse will be less.
The amount of impulse will be the same either way.





5 . A fast-moving massive car has a head-on collision with a slow-moving light car. Upon which is the impulse greater? [Hint]
The massive car.
The light car.
Impulse is the same on both.
More information is needed to correctly answer this.

acceleration.
impulse.

10 km/h.
1000 km/h.
None of these are correct.

0.5 m/s.
1 m/s.
1.5 m/s
