Respuesta :
[tex]\bf s(t)=4-2t\implies \cfrac{ds}{dt}=0-2\implies \left. \stackrel{v(t)}{\cfrac{ds}{dt}=-2} \right|_{t=6}\implies -2[/tex]
Answer:
Velocity, s'(t)=-2
Step-by-step explanation:
It is given that,
The position of an object at time t is given by following equation :
[tex]s(t)=-4-2t[/tex]
We need to find the instantaneous velocity. We know that velocity is given by :
[tex]v=\dfrac{ds(t)}{dt}[/tex]
or
[tex]s'(t)=-2[/tex]
So, the instantaneous velocity at t = 6 seconds is -2 m/s i.e. s(6) = -2 Hence, this is the required solution.
