Answer:
[tex]-10ms^{-1}[/tex]
Step-by-step explanation:
The position function is [tex]s(t)=1-10t[/tex].
The instantaneous velocity at t=10 is given by:
[tex]s'(10)[/tex].
We first of all find the derivative of the position function to get:
[tex]s'(t)=-10[/tex]
We now substitute t=10 to get:
[tex]s'(10)=-10[/tex]
Therefore the instantaneous velocity at t=10 is -10m/s
