I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.
First row, KE = 0
Second row, KE = 220500 J
Third row, KE = 183750 J
Fourth row, KE = 205800 J
That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.
For a pendulum with a massless rope 'L' meters long, swinging through
a small arc, the period of the swing is
2 π √(L/g) seconds .
and it doesn't depend on the mass of the thing on the end of the rope ...
that could be a pebble or a bus.
For the girl on the 2.5-m rope,
Period = (2 π) √(2.5 / 9.8) = 3.17 seconds
Frequency = 1 / period = about <em> 0.315 Hz .</em>
