Here's how I would do it:
How far does he have to go to catch the bug ? <u>23.8 meters</u>
How soon does he want to get there ? <u>1.8 seconds</u>
What speed does he need ? (23.8 m) / (1.8 sec) = <u>13.222 m/sec</u>
What speed is he flying now? <u>3.7m/s</u>
How much does he need to increase it ? (13.222 - 3.7) = <em>9.5 m/s</em> faster
A :-) F = mv^2 by t
Given - m = 10 kg
r = 10 m
v = 10 m/s
Solution -
F = mv^2 by t
F = 10 x 10^2 by 10
F = 10 x 100 by 10
( cut 10 and 10 because 10 x 1 = 10 )
F = 100 N
.:. The centripetal force is 100 N
The period of the pendulum depends only on the length from the pivot to the "center of mass". So if the string has no mass, then the amount of mass on the end doesn't make any difference.
But if the pendulum is suspended on, say, a chain with mass, then the more mass on the bottom, the lower the center of mass is, and the longer the period is.
Answer: i didnt look at your question its to long
