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

Tell me
ds/dt=?

Answer 2

Yah

Answer 3

U know
d2/dt=0

Answer 4

ok

Answer 5

Because derivative of any constant is =0

Answer 6

ok

Answer 7

U know 2 is a number. So 2 is a constant. Right?

Answer 8

yah 2 is a constant and thus the derivative is zero.. so would zero be the answer?

Answer 9

No

Answer 10

This problem is just confusing me..

Answer 11

c
d(6t)/dt=6*dt/dt=6*1=6

Answer 12

I don't understand

Answer 13

ds/dt=d(2)/dt-d(6t)/dt

Answer 14

Nd velocity v=ds/dt

Answer 15

ok... FLVS doesn't explain derivatives very well sorry

Answer 16

Plz tell me ur problem specifically

Answer 17

I wanna help u !

Answer 18

Dont u know
Velocity v=ds/dt

Answer 19

Thanks for the help.. What I think they want is a derivative question that involves solving with the t=2. This is why im confused

Answer 20

I know that v=ds/dt

Answer 21

U know v=-6

Answer 22

So v is constant

Answer 23

After time t=2 sec the velocity is v=6

Answer 24

Nd it is negative

Answer 25

ok... I think I was making it a lot more complicated than it rreally was

Answer 26

Negative sign indicates direction of velocity

Answer 27

Ok

Answer 28

Thanks!

Answer 29

U r most welcome !!

Answer 30

Anyway may i know the name of ur country?

Answer 31

Just for curiosity
