Answer:
198.505 N
Explanation:
Since this can be modeled as a point mass swinging system with the radius being the arm length. So r = 0.6m.
Also at it's lowest point the ape has a horizontal velocity v = 3.7 m/s. This velocity could result in a centripetal acceleration a, creating tension on the branch.
According to Newton's 2nd law, F = ma. So the tension is:
Solution:
The gravitational force that acts on the bicycle system is
Now the force, that is the gravitational force is related to mass of the system and the acceleration due to gravity of the system, 'm' and 'g' respectively.
Therefore, we can write
500 = m x 10 (since , g = 10 m/s-s)
∴ m = 50 kg
Now the net vertical force acting on the student bicycle system is 0. And the vertical acceleration of system is also 0. The total horizontal force acts to the right of the system. So by Newton's 2nd law of motion, we can write
Therefore
Hence (C) is correct option.
It shows that acceleration of particle M is directly proportional to its displacement and its direction is opposite to that of displament. Thus particle M performs simple harmonic motion but M is projection of particle performing U.C.M. hence S.H.M. is projection of U.C.M. along a diameter, of circle.
The given statement is true.
<u>Explanation:</u>
Professional assessments are nothing but training a person to do or complete a work in a good and professional manner. Professional assessments are one kind of way to make the person or individual do all the respective work in a skillful and professional manner.
They are a reliable method to improve certain qualities of an individual and can be considered as the only main method to determine the health related fitness of an individual. There are no other health methods that can be used to determine the heath level of an individual. Hence the above provided statement can be concluded as true.
Answer:
angular velocity
Explanation:
In physics the quantity represented by is the <u>angular velocity, </u>the units of the angular velocity are radians/second.
This is a quantity that represents the speed when the movement of an object follows a circular path.
Mathematically defined as follows:
Where is the period, the time it takes to complete a lap.
