Question

calculating instantaneous velocity

Answer 1

By determining the average velocity successively over the time intervals
[1, 1.1], [1, 1.01], [1, 1.001], [1, 1.0001] ,
estimate the instantaneous velocity, v(1), of
the particle at time t = 1.

Answer 2

the original equation is \[5t ^{2}-8t+2\]

Answer 3

do I just find the derivative of that and substitute t for 1?

Answer 4

got the answer. I'm so smart :)
