Answer:
d = 39.7 km
Explanation:
initial position of the boat is 45 km away at an angle of 15 degree East of North
so we will have
after some time the final position of the boat is found at 30 km at 15 Degree North of East
so we have
now the displacement of the boat is given as
so the magnitude is given as
So, <u>the value of the work is approximately 84.65 J</u>.
<h2>Introduction</h2>Hi ! Here I will help you to discuss the subject about work that caused by force in amount value of angle. Work is affected by the force and displacement.
- If related to the magnitude of the force, the amount of work will be proportional to the magnitude of the applied force. Thats mean, if the value of the force that applied on it is greater, then the value of the work will be greater.
- If related to the magnitude of shift, the amount of work will be proportional to the magnitude of shift of object. Thats mean, if the value of the shift on it is greater, then the value of the work will be greater.
The work done by a moving object can be expressed in the equation:
If the Angle Is Ignored
If the Angle Effect on Work
With the following condition:
- W = work that done by object (J)
- F = force that applied (N)
- s = shift or distance (m)
= angle of elevation (°)
We know that :
- F = force that applied =
N
- s = shift or distance = 84.9 m
What was asked ?
- W = work that done by object = ... J
Step by step :
So, the value of the work is approximately 84.65 J.
