Joey and his bike have a mass of 47.0 kg. He going to ride onto a ramp moving a a steady 9.3 m/s and he will not lose any speed on the ramp.

The ramp is angled at 32.5° to the ground.

You are to determine the horizontal distance he will travel as a projectile before landing on a ramp at the same height as the ramp from which he jumped

The gravitational field strength on the planet where this took place is 12.20 m/s/s.
