Jason knows that the equation to calculate the period of a simple pendium T=2π√L/8, where T is the period, L is the length of th
e rod and g is the acceleration due to gravity. He who knows that the frequency (f) of the pendulum is the reciprocal of period. How can he express L in terms of g and f?

Answer:
The velocity is in positive x -direction
The speed is
Explanation:
From the question we are told that
The distance from the house to truck is D = 20 m
The distance traveled back to retrieve wind-blown hat is d = 15
The distance from the wind-blown hat position too the truck is k = 20 m
The total time taken is t = 75 s
Generally when calculating the displacement the Justin's backward movement to collect his wind - blown hat is taken as negative
Generally Justin's displacement is mathematically represented as
=>
Generally the average velocity is mathematically represented as
=>
=>
Generally the distance covered by Justin is mathematically represented as
=>
=>
Generally Justin's average speed over a 75 s period is mathematically represented as
=>
=>
Answer:
1000 mph
Explanation:
P = Perimeter = 24000 mi
r = Radius of the equator
t = Time taken to complete one rotation = 24 h
Perimeter of a circle is given by
Angular speed is given by
Velocity if given by
The person would be going at a speed of 1000 mph
