CP Ella and Lily Physics: Position, Velocity, and Acceleration

Ella starts at her friend Bruno's house and travels 55m. She realizes she forgot to say goodbye to his niece Isabella, so she heads back, says goodbye, and leaves again. She returns to her initial location of 55m outside the house.

What is the distance that Ella traveled?

Ella starts at her friend Bruno's house and travels 55m. She realizes she forgot to say goodbye to his niece Isabella, so she heads back, says goodbye, and leaves again. She returns to her initial location of 55m outside the house.

What is Ella's total displacement?

Lily is skateboarding down a hill. Her initial velocity is 10 m/s. She accelerates at a constant rate and her final velocity is 20 m/s.

What is her average velocity?

Lily is skateboarding down a hill. Her initial velocity is 10 m/s. She accelerates at a constant rate and her final velocity is 20 m/s. It took 10 seconds to get this change of velocity.

What is her displacement?

Lily is 15 meters from a body of water when a monster jumps out. She runs at a velocity of 10m/s in the positive direction for 20s.

How far is she from the body of water if she runs at a constant velocity?

Starting at home on Earth, Lily and Ella get in a spaceship and travel 128720 meters away from Earth to get some food at a space station. Then, they check out an asteroid another 3218 meters further away from their home on Earth. After they check out the asteroid, their friends drop them off back at home on Earth.

What is their total displacement in miles?

1609 meters = 1 mile

Lily is running to get to see her favorite musician in concert. If she does not increase her velocity by a factor of 4 she will be late!!!

What changes could she make that would result in 4 times her velocity?

(two correct answers)

• 1/2 the distance in 1/8 the time

• 6X the distance and 24X the time

• 24X the distance and 6X the time

• 1/8 the distance in 1/2 the time
