Question

derivative problem

Answer 1

ok, it looks like the average velocity is 20/5 or 4 cm/sec

now we need an expression for the instantaneous velocity
that means we need to take the derivative (with respect to time "t")
of
t^2 - t+10

can you do that ?

Answer 2

2T-1

Answer 3

What exactly does "repect to the time of" mean
