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

First we need to know how many miles per hour they drove the first time. This would be found by division. 168/3.5=48
Then we need to add 5 miles per hour for the average.48+5= 53
Next we need to multiply 2 1/4 by the new miles per hour 53*2.25=119.25
After that we need to know how many miles they drove 119.25+168=287.25 miles.
Finally to get an improper fraction we need to change 287.25 miles to it.
We already have 1/4 for .25 so we multiply 287 by 4 and add it to the 1/4 we already have and it makes it out to be 1149/4
Hope this helps!
