Question

if displacement of the body is given by s=9t+3t².find it's velocity

please give in easy way​

Answer 1

Displacement Equation: s = 9t + 3t^2

Velocity equation can be derived from the displacement equation by differentiating it once with respect to time.

That is, If velocity is denoted by 'v' and displacement by 's' then:

v = d(s)/dt

= d(9t+3t^2)/dt

= 9 + 6t

Hence, the velocity equation is given by v=9+6t
