Question

If a ball is thrown into the air with a velocity of 40ft/s, its height(in ft) after t seconds is given by y=40t-16t^2. Find the velocity when t=2.

Answer 1

Do you understand derivatives?

Answer 2

In this case, the velocity is the derivative of the height.

Answer 3

So they are just asking you to find \(\frac{dy}{dt} (2)\).

Answer 4

i dont really understand, could you show me?

Answer 5

Do you know how to differentiate? (Find the derivative)

Answer 6

i think so. The derivative of f^1(a)
