a.
To find the rate of change of wind speed between 6 A.M and 8 A.M.
a.

Answer to Problem 3.19EP
The wind speed is 5.
Explanation of Solution
Given information:
The graph is
Formula used:
where,
Calculation:
Wind speed at 6 AM,
Wind speed at 8 AM,
Substituting
So,
b.
To find the greater change in wind speed.
b.

Answer to Problem 3.19EP
Graph shows greater change in wind speed between 8 A.M and 10 A.M. and wind speed is 10.
Explanation of Solution
Given information:
The graph is
Formula used:
where,
Calculation:
Graph shows greater change in wind speed between 8 A.M and 10 A.M. Wind speed at 8 AM,
Wind speed at 10 AM,
Substituting
So,
c.
To explain a storm came through at some point during the day.
c.

Answer to Problem 3.19EP
Graph shows wind speed at 10 A.M., 12 P.M and 2 P.M wind speed is 20.
These are points at which storm came.
Explanation of Solution
Given information:
The graph is
Explaination:
Wind speed at 10 AM is 20
Wind speed at 12 PM is 20
Wind speed at 2 PM is 20
Graph shows greater wind speed at 10 AM, 12 PM, and 2PM
Hence, these are points at which storm came.

Passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: where h is the height of the last passenger above the ground measured in feet and t is the time of operation of the ride in minutes. What is the height of the last passenger at the moment of the power outage? Verify your answer by evaluating the sine function model. Will the last passenger to board the ride need to wait in order to exit the ride? Explain.arrow_forward2. The duration of the ride is 15 min. (a) How many times does the last passenger who boarded the ride make a complete loop on the Ferris wheel? (b) What is the position of that passenger when the ride ends?arrow_forward
- 3. A scientist recorded the movement of a pendulum for 10 s. The scientist began recording when the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left (negative displacement) several times. The pendulum took 4 s to swing to the right and the left and then return to its resting position. The pendulum's furthest distance to either side was 6 in. Graph the function that represents the pendulum's displacement as a function of time. Answer: f(t) (a) Write an equation to represent the displacement of the pendulum as a function of time. (b) Graph the function. 10 9 8 7 6 5 4 3 2 1 0 t 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 -1 -5. -6 -7 -8 -9 -10-arrow_forwardA power outage occurs 6 min after the ride started. Passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: h = −82.5 cos (3πt) + 97.5 where h is the height of the last passenger above the ground measured in feet and t is the time of operation of the ride in minutes. (a) What is the height of the last passenger at the moment of the power outage? Verify your answer by evaluating the sine function model. (b) Will the last passenger to board the ride need to wait in order to exit the ride? Explain.arrow_forwardThe Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board over the course of the 15 min ride.
