Question

Velocity question

Answer 1

Find the derivative: velocity = dx/dt

Answer 2

Well that equation you are given looks to be the position equation

To get velocity, we need to take the derivative of this equation

Answer 3

Then then take the derivative of the newly derived velocity equation to find the acceleration.

Answer 4

@johnweldon1993 so i took the derivative and got 2.92-2t

Answer 5

then plug in 3.10 for t but thats not the right answer

Answer 6

You tried putting in -3.28 for an answer and it was incorrect?

Answer 7

oh thats right... i swear i put that in already..haha

Answer 8

so the acceleration is jsut the derivative of the velocity?

Answer 9

Lol perhaps forgot the negative sign? Regardless, yes now just take the derivative of the velocity to find the acceleration

Answer 10

so 2?

Answer 11

Not quite...

Answer 12

oh forgot the - again

Answer 13

thanks for your help

Answer 14

Anytime!
