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
