1. Egg Drop Experiment strategies

Ya, thats really good. If it was slightly conical it would definitely stop the egg from slipping down on impact. The paper in a conical shape wouldnt b quite as strong as cylindrical though
2. Egg Drop Experiment strategies

Unless ur allowed drop it onto the paper, no. In that case u could make a slide. Id say work on ur parachute design. Did u make a hole in the top?
3. Egg Drop Experiment strategies

U can make a parachute out of the paper. Sounds silly but it works
4. 1D Kinematics Again

U dont have or need a time variable so thats the wrong equation of motion. This 1 shud work better: v^2 = v_0^2 + 2ax The other 1s r listed here if u need em: http://en.wikipedia.org/wiki/Equations_of_motion
5. Motion on incline

well the ball is gonna accelerate as it rolls down the plane. it sounds like ur assumin the velocity stays the same
6. Skydiving problem

Well, u got the right answer for v_terminal anyway in ur 1st post. (v^2 = 13.06) U still need more info about before the parachute was opened to get the drag just after. The drag force u calculated (783. 6) is the drag force when the skydiver achieved v_terminal, which is a little while after...
7. Friction Problem

I dont see what else u could do. Seems perfect 2 me
8. Newtons laws again

The only thing i regognise there is 1/2at^2. This wudv worked:
9. Projectile Motion, A study of height and time

How do u no ur wrong? Looks ok 2 me unless im makin exactly the same mistake. Mayb ur lookin under the wrong chapter at the back of the book 4 ur answers!?
10. Kinematics- ball thrown

Well u just hav 2 use the same equations of motion The usual convention for these 1s is up is positive and down is negative so the initial speed u is a positive num since in the up direction. The displacement s will be -100 and g is -9.81. Putting in the numbers: s = u*t - 0.5*g*t^2 -100 =...
