That's a typo...if the acceleration of gravity is -16ft/s^2??? Maybe basketball on Mars :P
Free fall equation result from integration of the acceleration equation with respect to time...
a=g
v=gt+v0
h=gt^2/2+v0t+h0 where v0 and h0 are initial velocity and height respectively..
Since acceleration, g, is about -32ft/s^2 not -16ft/s^2 you get:
h=-16t^2+36t+4 for your height equation.
h(2)=12 ft
Answer:
the right ones are a c and d maybe
Step-by-step explanation:
these are probably wrong but I need my points so figure it out.
Answer: Between x = -2 and 0.
Explanation: Let's first look for an interval where the gradient is decreasing. That is, if we were given the function for each curvature or line, the derivative would be negative.
We see that only two places have a decreasing gradient (between 0 and -2 and 2 and 4).
Now, the question asks for a non linear line. So, we want to look for a curve instead of a line and thus, the only viable interval is between -2 and 0.
