Answer:
Acceleration due to gravity will be
Explanation:
We have given length of pendulum l = 55 cm = 0.55 m
It is given that pendulum completed 100 swings in 145 sec
So time taken by pendulum for 1 swing
We have to find the acceleration due to gravity at that point
We know that time period of pendulum;um is given by
So
Squaring both side
So acceleration due to gravity will be
You have three known variables:
Acceleration -
Time -
Initial Velocity -
For the first part of your question:
For the second part of your question:
This still needs to be converted to m/h:

Answer:
d = 90 ft
Explanation:
Here in each swing the distance sweeps by the swing is half of the initial distance that it will move
So here we can say that total distance in whole motion is given as
since it is half of the distance that it will move in each swing so it would be a geometric progression with common ratio of 1/2
so sum of such GP is given by the formula
