Question

The position of an object at time t is given by s(t) = -2 - 6t. Find the instantaneous velocity at t = 2 by finding the derivative.

Answer 1

@hartnn @paki

Answer 2

have you learnt derivatives ?

Answer 3

yes

Answer 4

so could you find the derivative of s(t) ?

Answer 5

would that be
\[\frac{ -2-6(t+h)-2-6(t) }{ ? }\]

Answer 6

?=h

Answer 7

thats by definition, haven't you taught direct formulas ?

Answer 8

like
\(\Large
\dfrac{d}{dx} (x^n) = n x^{n-1}\)

Answer 9

and derivative of a constant is simply 0

Answer 10

so how would i right thaat out with the numbers?

Answer 11

see if that makes sense ^^
