Velocity is the derivative of the position with respect to time. Are you given the position with respect to time. All you have to do is differentiate.

Do I have to plug in the 2?

v(t)=ds/dt v(t)=12t+240 v(2)=12*2+240=264 feet/second

You plug the 2 into the derivative.

You mean you have to use: \[ \sin(x/2) = \pm\sqrt{\frac{1\cos(x)}{2}} \]?

In that case split it into: 1 + 12

you're going to have to split it regardless.

just differentiate the given function with respect to 't' It will give you velocity as a function of 't'. just plug in the required value i.e '2' to obtain velocity at time 2 seconds...
