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.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
