My strategy for solving any projectile motion problem. You need to split the variables in to the x and y directions and solve for time. Sounds simple and it really is, usually.

Professor Lewin discusses projectile motion and asks his students if a monkey falling out of a tree could dodge a hunter's bullet. He then tests the idea with a stuffed monkey. Watch and find out if the monkey is safe. (04:41)

More on two-dimensional projectile motion and completing our first example from parts 1 and 2. This video, which is suitable for high school students, starts with a black screen because the instructor, in his easy, conservsational tone, uses it as a ...'chalkboard.' Run time 09:13.[more]

The second part of the last projectile motion problem. This video, which is suitable for high school students, starts with a black screen because the instructor, in his easy, conservsational tone, uses it as a 'chalkboard.' 4:06

If a bullet is dropped simultaneously from the same height that another bullet is fired from a gun, which will hit the ground first? The mythbusters perform the experiment to find out. Check it out (02:52).

If you can drop it, you can throw it. Dr. Carlson throws stuff around to show how projectiles fall and how their horizontal and vertical components are independant of one another (04:44)

Another example of a 2-dimensional projectile motion problem. This video, which is suitable for high school students, starts with a black screen because the instructor, in his easy, conservsational tone, uses it as a 'chalkboard.' Run time 09:05.

Using vectors to solve 2-dimensional projectile motion problems. This video, which is suitable for high school students, starts with a black screen because the instructor, in his easy, conservsational tone, uses it as a 'chalkboard.' Run time 09:18.

Which will hit the ground first: A ball dropped, or a ball thrown horizontally? This video answers the question with the unexpected answer "both, at the same time". Run time 02:23
