here are some shortcuts to find ............... in motion in 1 dimension

1) to find the vel. in b/w the distance travelled

V₁= {v² + (v²- u²/n)}^1/2

2) a bullet is fired with certain vel. into a block of wood . it loses 1/nth of its initial speed after travelling a dist. x in the block . determine the total dist. penetrated by it before coming to rest....

ans)

x' = {N²/ 2n - 1} x

where N is the amt of speed it loses (eg. if 1/10 th loses then N = 10)

I always like to walk in rain as no one can see me crying there :( frnds are like diamonds , if u hit them , they don't break but they slip frm ur hands -----It is better to be hated for what you are than to be loved for what you are not.---- *****wen love and skill work together--expect a masterpiece*****
