The distance in feet that a ball rolls down an incline is modeled by s(t) = −2t^2 − 2 , where t is seconds after the ball begins rolling. Find its instantaneous velocity at t = 4 seconds.

v(4) = ____

Respuesta :

Answer:

-16

Step-by-step explanation:

pretty sure its the right answer, we did this a week ago in class so it may be wrong.

so first u gotta find the derivative of s(t) to get the vel equation. the derivative of s(t):

s(t)'= -4t, which is the vel equation

s(t)'=v(t)

v(4)=-4(4)

which equals -16
