PLEASE HELP At a time t after being projected from the ground, a projectile is displaced x units horizontally and y units vertically above its point of projection. (Use any variable or symbol stated above along with the following as necessary: g for the acceleration due to gravity.)

What are the horizontal and vertical components of the initial velocity of the projectile?

At the instant the projectile achieves its maximum height above ground level, how far is it displaced horizontally from the launch point?

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.)
