Questions and Answers

What is the initial vertical velocity of Buddy when he is shot out of the cannon?

  • 69.28 m/s
  • 40 m/s (correct)
  • 30 m/s
  • 80 m/s

    • What is the final horizontal velocity of Buddy after being shot out of the cannon?

  • 40 m/s
  • 69.28 m/s (correct)
  • -69.28 m/s
  • -40 m/s

    • Why is the final vertical velocity of Buddy -40 m/s?

  • Due to air resistance
  • To follow a symmetrical path (correct)
  • Due to a change in acceleration
  • Because of gravity
