• A body travels with a positive velocity and a positive acceleration.

• A body travels with a positive velocity and a negative acceleration.

• A body travels with a constant velocity and a time-varying acceleration.

Starting from rest, a particle is accelerated at a constant rate of 5.0 m/s². Which one of the following statements accurately describes the motion of this particle?

• The particle travels 5.0 m during each second.

• The particle has a constant speed of 5.0 m/s.

An elevator is moving upward with a speed of 11 m/s. Three seconds later, the elevator is still moving upward, but its speed has been reduced to 5.0 m/s. What is the average acceleration of the elevator during the 3.0 s interval?

• 2.0 m/s² upward

• 2.0 m/s² downward

• 5.3 m/s² upward

A fighter jet lands on an aircraft carrier at a velocity of v. The jet requires a distance, D, to stop on the aircraft carrier. How long does it take the jet to stop after it lands?

• D / 2v

• D² / v

• D / v

• 2D / v

Johan just goes and throws his physics textbook in the air at speed v. Wow, what a rebel. He finds that the book reaches a maximum height of H. How high would the book go if he instead were able to throw the book upwards with a speed of 4v?

• 8H

• 4H

• H

• 16H

In order to train to fight Vegeta, Goku trains on King Kai’s planet, a planet with ten times Earth’s gravity; meaning the planet has an acceleration due to gravity of 10g. Goku drops a dragon ball on King Kai’s planet (which has 10 times gravity) and the dragon ball falls a height H in one second. How long would the same dragon ball fall in 1 second on Earth?

• H

• 10H

• H/100

• H/10
