The relationship between the density of ocean water and the formation of deep currents. Difference in the tempature and salinity and the resulting differences in density cause variations int he movement of deep currents. For example, the deepest current , The Antarctic Bottom Water, is denser than the North Atlantic Deep Water. Both currents spread across the ocean floor as they flow toward eachother. Because less dense water always flows on top of denser water, The north Atlantic Deep Water flows on top of the Atlantic Bottom Water when the currents meet.

The maximum amount of work that the hammer can do while falling to the ground is equal to its variation of gravitational potential energy, which is given by:
where m is the mass of the hammer, g is the gravitational acceleration, h is the variation in altitude of the hammer.
Plugging the data of the problem inside the equation, we find
(9.81%20m%2Fs%5E2)(2%20m)%3D98.1%20J)
where m is the mass of the hammer, g is the gravitational acceleration, h is the variation in altitude of the hammer.

"Contact" means "touching". A contact force can't act on an object unless
they're touching. Friction is a contact force.
Gravitational forces pull masses together even if they're not touching.
Magnetic forces pull a piece of iron toward a magnet even if they're not touching.
Gravitational and magnetic forces are "non-contact" forces.

This is a very clever and interesting exercise. I'm typing on a little telephone screen and it would take me a week to explain my reasoning, so I can only give my proposed answer. It's . . . 60 degrees above the horizon.
