What is the best angle to do a long jump from a 20 metre running start.

2. Relevant equations

What is the terminal velocity of the run up?

Maximum height of the jump

Horizontal and verticle components

3. The attempt at a solution

Hello there, I am doing an EEI on the physics of long jumping and I'm not exactly sure what physics are needed to figure out the best angle of the long jump.

I have video taped myself doing long jump from a 20 metre runup and a long jump. After looking at the video footage, I calculated my takeoff angle to be approximately 25 degrees to the hoirzontal.

Also I assume that my terminal velocity of my runup is also the inital velocity of my trajectory during the actual jump.

I have also taken to account the my center of mass is in my hip position. So I don't have a complete trajectory. Because at the beginning of my jump my waist is about 80cm off the ground but when I land. I tuck my legs in so it's basically or close to 0cm off the ground. Also tucking the legs in gives me more air time so I travel further.

The problem is that I don't know exactly what I'm looking for. What do I put in my introduction? what do i need to know and what I don't need to know? What am I missing?

Help is greatly appreciated... thanks guys/gals
