Answer:
T = 4.0 s
Step-by-step explanation:
The period of a simple pendulum is given by

where l = length of the pendulum
= 4 m
g = acceleration due to gravity
= 9.8 m/s^2

Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
