we know that
The scalar magnitude of the velocity vector is the speed. The speed is equal to
in this problem we have
substitute in the formula
therefore
<u>the answer Part a) is</u>
the speed is equal to
<u>Part b) </u>Find the velocity
we know that
<u>Velocity </u>is a vector quantity; both magnitude and direction are needed to define it
in this problem we have
the magnitude is equal to the speed
therefore
<u>the answer Part b) is</u>
the velocity is
Part c)
we know that
the acceleration is equal to the formula
in this problem we have
substitute in the formula
therefore
<u>the answer Part c) is</u>
the acceleration is
This is an example of negative acceleration
Answer:
62.2°
Step-by-step explanation:
If a wire used to stabilize something is 115 feet long runs from
the top of a radio tower to a point on the ground 50 feet from the tower's base, then;
The set up will form a right angle triangle as shown
The Adjacent side = The base of the tower = 50 feet
The hypotenuse = length of the wire = 115feet
The Height of the tower = Opposite side of the set up.
theta = angle that the wire make with the ground
Using the SOH CAH TOA trigonometry Identity:
According to CAH;
Cos(theta) = Adjacent/Hypotenuse
Cos(theta) = 50/115
Cos theta = 0.435
theta = arccos 0.435
theta = 62.2°
