An advanced freefall acceleration problem involving 2 parts and 2 objects. Problem: You are wearing your rocket pack (total mass = 75 kg) that accelerates you upward at a constant 10.5 m/s^2. While preparing to take pictures of the beautiful view, you drop your camera 5.0 seconds after liftoff. 5.0 seconds after you drop the camera, (a) what is the camera's velocity and (b) how far are you from the camera?

A FreeFall Problem That You Must Split Into Two Parts
Flipping Physics posted a video in Kinematics
This is a complicated freefall problem where you have to identify that the velocity at the top of the path is zero in the ydireciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem into two different parts. A classic freefall acceleration example problem. Content Times: 0:45 Reading the problem 1:12 Translating the problem to physics 3:04 Starting with the whole event 4:36 Splitting the problem into two parts 6:06 Solving part 1: Going up 8:17 Finishing the problem 9:05 An alternate solution 9:38 The review [url="http://www.flippingphysics.com/freefallproblem.html"]Want Lecture Notes?[/url] Next Video: [url="http://www.flippingphysics.com/droppingdictionaries.html"]Dropping Dictionaries Doesn't Defy Gravity, Duh![/url] Previous Video: [url="http://www.flippingphysics.com/commonfreefallpitfalls.html"]Common FreeFall Pitfalls[/url]

Average Velocity Example Problem with Three Velocities
Flipping Physics posted a video in Kinematics
This example problem works through finding the average velocity when we have multiple parts to the givens. It involves splitting the given information into separate parts, finding the total displacement, the total time and then the total average velocity.
