Asmall sphere of mass m is launched horizontally over a body of water from a height h above the water and with a launch speed v0. determine expressions for the following in terms of m, v0, h, and g. air resistance is negligibly small.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?
