Find the instantaneous velocity (intro to analysis)?
Suppose the position of an object moving in a straight line is given by s(t) = 5t^3 - 7t^2 + 9.
Find the instantaneous velocity when t=7.
The answer I got was incorrect so I need some help. Thank you!
You take the limit of [ f(x+h) - f(x) ] / h

Derivative of position with respect to time is 15t^2 - 14t.
Plug t = 7 into that. This is the instantaneous velocity at that moment.
