Question

The correct relation to find out the velocity (where t = time, d = distance and v = velocity) is (a) v = t × d (b) v × d = t (c) v × t = d (d) v = t + d​

Answer 1

t=ax2+bx

Differentiate w.r.t time

1=2axdtdx+bdtdx

dtdx=2ax+b1

V=2ax+b1...(1)

a=dtdV=(2ax+b)2−(2adtdx)

a=(2ax+b)2−2av....(2)

Substiting 2ax+b1=V in (2)

we will get, a=−2av3

Answer 2

v x t = d
v = d/t

(Option c is correct)
