Question

Velocity help:

Answer 1

If a ball is thrown into the air with a velocity of 49 ft/s, its height (in feet) after t seconds is given by \[y = 49t - 16t^2\]. Find the velocity when t = 2.

Answer 2

Just curious but how does one obtain the ambassador badge?

Answer 3

Like be an ambassador from another math site or what? :/

Answer 4

Not the place to ask that, there is an ambassador section.

Answer 5

I am trying to remember back to this sort of question lol, gimme a sec luilui.

Answer 6

You need to take the derivative with respect to time.

Answer 7

dy/dt gives velocity where y is the displacement

Just evaluate it and put t=2.

Answer 8

Yerp,
\(\large{v=\frac{dy}{dt}}\)

And just like Aravind said, when you have done this, you just plug in your given value and voila :D

Answer 9

Alright, thanks guys :)

Answer 10

Nu problemo brubru.
