Explanation:
In order to calculate the displacement of the airplane you need only the information about the initial position and final position of the airplane. THe initial position is at the origin (0,0,0) and the final position is given by the following vector:
The displacement of the airplane is obtained by using the general form of the Pythagoras theorem:
(1)
where x any are the coordinates of the final position of the airplane and xo and yo the coordinates of the initial position. You replace the values of all variables in the equation (1):
hence, the displacement of the airplane is 3.45*10^4 m
Answer:
a
b
Explanation:
From the question we are told that
The diameter of the Ferris wheel is
The period of the Ferris wheel is
The mass of the passenger is
The apparent weight of the passenger at the lowest point is mathematically represented as
Where is the centripetal force on the passenger, which is mathematically represented as
Where is the angular velocity which is mathematically represented as
substituting values
and r is the radius which is evaluated as
substituting values
So
W is the weight which is mathematically represented as
So
The apparent weight of the passenger at the highest point is mathematically represented as
substituting values
