I am really trying hard to work through this one. Could you suggest a direction I should take? Perhaps I should not be multiplying at all. Since the acceleration due to gravity is 9.8ms^2 I should subtract that from the 22f/s since the gravity is "retarding" the human. Am I getting anywhere here?

It would be 9.8m/s^2 So, -32.15f/s^2 right? Now I convert 15mph to 22 f/s. Now I multiply 22f/s x 32.1 f/s^2 = 706 f/s^2 Is this right?

Homework Statement Hi guys, I am working through a very long problem and I am stuck at this part. So I have a 70kg human being launched at a 90 degree angle at 15mph. I need to figure out how high in the air he will get before velocity reaches zero again and he begins to fall. Homework...

Okay perfect, so I looked up the width of that model of car and estimated the crash test dummy is about 1.5 car widths in the air before he falls. The scene is in slow motion so I timed the dummy being ejected to when he falls (about 2 seconds). I'm having a a hard time figuring out how to...

Ive got the slow motion part figured out. How do I go about this speed/time plot?

Homework Statement Watch the crash test video , and determine the following: 1. How fast is one of the crash test dummies thrown forward (the crash at :34 seconds) ? Pick either one, and be clear how you estimate this. 2. Assuming the speed you got from part (1), how high would a different...
