Question

The position of an object at time t is given by s(t) = -4 - 2t

Answer 1

Find the instantaneous velocity at t = 6 by finding the derivative.

Answer 2

Can you take the derivative first?

Answer 3

I'm not sure how to @AravindG

Answer 4

Differentiate -4 - 2t with respect to t.

Answer 5

would it be -2? @AravindG

Answer 6

Yes! Good work!

Answer 7

so is negative 2 the answeer???????????? @AravindG

Answer 8

We got instantaneous velocity as v=-2 . There are no t terms involved so velocity will be constant and equal to -2 for any value of t. Hence -2 is the answer.
