#### Solution Preview

The key to solving most of the projectile motion problems is conservation of energy.

For example, if we are asked to find the final velocity just before touching ground, for a body of mass m thrown with a velocity V, proceed as follows.

We are "Throwing" the body; this means we did work on the body--> or in other words we gave it some energy and with that energy it is flying.

As energy can neither be created or destroyed, we must take the final energy ...
