A simple pendulum consists of a 4.9-kg mass attached to a string. The pendulum is pulled to the right and held at rest so that it is 2.08 m above the lowest point in its swing. If you let it go from this point, how fast (in m/s) is it traveling at the lowest point of its swing (on the initial pass)

6.384 m/

Explanation:

The velocity is given by;

We know;

PE= mgh

KE= 1/2 m

but KE=PE

==> 1/2 m =mgh

==> 1/2 =gh

==>

puting g=9.8 m/sec2

h=2.08 m

==> =

no

sodium is solid at rt

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
