Figure (b) shows the size vs. age graph of our universe. One can
consider it as an x-t graph and read from it the expansion rate of
the universe (velocity) and how the rate changes with time
(acceleration). Are the statements below correct? (And explain)
A. The universe is always expanding.
B. 10 billion years ago, the expansion rate of the universe was
increasing.
C. The universe will be expanding slower 10 billion years later
than it is now.

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

hello,
I need help with this for a homework problem soon. this is
just one question with multiple parts i'd greatly appreciate
it.
a) (5 pts) During free fall, after some object has been thrown upwards, the velocity momentarily goes to zero at the highest point in the trajectory. Some people (falsely) believe that the acceleration of the object also becomes zero at the highest point in the trajectory. Briefly explain what the motion of the object would look like...
