Mechanics of Harry Potter 1

Classical Mechanics Level 2

If Dumbledore is stood on a balcony 25m above the ground and Harry whips out his 'wand' and pricks Dumbledore in the back. Dumbledore, shocked with the pain is forced forward with initial horizontal velocity 1.5 m/s off the edge of the balcony. With air resistance being negligible (this is Hogwarts after all) how far away (horizontally) will Dumbledore land from the balcony?

[ Take gravity to be 10 N/m ]

4.0 m 60.5 m It's infintie as there's no gravity in Hogwarts 3.35 m
