What is the derivation of v²= u²+ 2as? |
|
Answer» v*2 = u*2 +2asSo now we have the eq.v = u +ats = 1/2 (u+v) ts = it + 1/2 at*2All three have t in them - it would be USEFUL to get RID of it. STARTING with the first eq. we can write: t = (v- u ) ÷a.this can be substitute d into second:s = 1/2( u+v) ts= 1/2 ( u+v) (v-u) ÷aExpanding the brackets , and multiplying out the 1/2 & a :2as = (u+v) (v-u) this rearranges to: v*2 = u*2 +2as |
