Question

which equation is also known as positive–velocity reaction​

Answer 1

Answer:

I hope it helpful

Explanation:

Equation of motion

Answer 2

Answer:

Equation for position velocity relation consider graph given in figure. We know that distance travelled s by a body

in time t is given by the area under line AB which is area of trapezium OABC. So we have

Distance travelled=s= Area of Trapezium

OABC

S=(sum of parallel sides) x height/2

=(OA+CB)x OC/2 since OA+CB=u+v and OC=t,

Then we gt

s=(u+v)t/2get,-- --(1) substituting the value of 't' in equation 1

from, velocity time relation,

t=v-u/a

we get, s=(u+v)/2(v-u)/2

or we have

v²=u²+2as

which is equation for position velocity
