The magnitude of the total displacement of her trip is 2.2 miles.
<h3>
Total displacement of Olivia's trip</h3>
The magnitude of the total displacement of her trip is calculated as follows;
Total east journey = 0.8 mi + 1.2 mi = 2 mi
Resultant displacement = √(y² + x²)
Resultant displacement = √(0.9² + 2²)
Resultant displacement = 2.2 mi
Thus, the magnitude of the total displacement of her trip is 2.2 miles.

Answer:
Explanation:
From the question, we can see that the elevator is at a constant speed, invariably, acceleration is zero. And thus, there is no external force acting in the man, asides from force of gravitation acting on the man between those 5s. Now, we solve the question using newton's second law of motion.
The second law of motion states that, "the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object."
Summation Fy = ma(y)
F(n) - F(g) = 0
F(n) - mg = 0
F(n) = mg
F(n) = 77*9.81
F(n) = 755.37N
We are given that,
We need to find 
when 
The equation that relates x and 
can be written as,
Differentiating each side with respect to t, we get,
Replacing the value of the velocity
The value of 
could be found if we know the length of the beam. With this value the equation can be approximated to the relationship between the sides of the triangle that is being formed in order to obtain the numerical value. If this relation is known for the value of x = 6ft, the mathematical relation is obtained. I will add a numerical example (although the answer would end in the previous point) If the length of the beam was 10, then we would have to
Search light is rotating at a rate of 0.96rad/s
Answer:
The apparent weight is the weight of the body minus the weight of the liquid displaced. The body will float only when both the weights are same. In this case, the given body of weight W is floating and hence the apparent weight is zero.
