Warm-up:
Harry and his friends are discussing quidditch strategy. They are wonderingif a player is flying horizontally on his broom at a constant velocity of 31 m/s
and he throws the quaffle (ball) straight up in the air with a velocity of 45
m/s, where will the quaffle land? (As always, ignore air resistance.)

Harry: “I think the quaffle will land on the ground in front of him.”
Ron: “The player will catch the quaffle.”
Hermione: “It will land behind him, of course.”
Malfoy: “The quaffle will disappear due to dark magic.”
