Assumption: You have a state-of-the-art pulsed fusion rocket engine capable of exhaust velocities of 500 km/s

Important Fact #1: Your spaceship must fly ahead of the asteroid at a distance of 1 times the asteroid's radius, 325m above the surface or 650m from the center of mass

Important Fact #2: The thrusters on this spacecraft are angled so that the ship's propellant just misses a "spherical" Apophis.

You'll need the rocket equation: https://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

You do not need Calculus

Make sure you title your email: "Spacetime Killer Asteroid Challenge"

Good luck!
