Question

The velocity of an object is v(t) = 28 - t$^2$, 0 ? t ? 6 where v is measured in meters per second and t is the time in seconds. Find the velocity v(5) (in m/sec) and acceleration a(3) (in m/sec$^2$) of the object when t = 5 and t = 3. v(5) = m/sec a(3) = m/sec$^2$ What can be said about the speed of the object when the velocity and acceleration have opposite signs? The speed of the object is but the rate of that

          The velocity of an object is
v(t) = 28 - t$^2$, 0 ? t ? 6
where v is measured in meters per second and t is the time in seconds. Find the velocity v(5) (in m/sec) and acceleration a(3) (in m/sec$^2$) of the object when t = 5 and t = 3.
v(5) = ____ m/sec
a(3) = ____ m/sec$^2$
What can be said about the speed of the object when the velocity and acceleration have opposite signs?
The speed of the object is ____ but the rate of that ____
