Imagine a box attached to a string, and the string is attached to the ceiling. If we say the string does have mass. Discuss how you might take into account a string that has mass. Would the tension be uniform throughout the string? Make sure to explain why or why not. If not, how would you also take that into account? Remember to cite any resources you might use.

9) A ball of mass m is attached to the ceiling via a string of length L. The ball is given a push to set it in motion. The ball then travels in a horizontal circle, such that the string makes and angle 0 with the vertical. It is observed that it takes time T for the ball to make one complete revolution. How can this experiment be used to measure the magnitude of the gravitational acceleration g. problem 9...
A heavy rope with length L and mass M is attached to the ceiling and is allowed to hang freely. (a) Find an expression for the tension in the rope at a point a distance y from the bottom, and use this to show that the speed of transverse waves on the rope is independent of its mass and length but does depend on the distance y according to the equation ?=??. (b) If L = 3.0 m and the...
1) A simple pendulum consists of an object with mass m attached to a string with length L. When the object swings upward making an angle of ? with respect to the vertical direction how much work is done by the tension force of the string? 2) Two friends are sitting in two canoes in the middle of a lake. Both canoes are initially motionless when one of the friends pushes the other canoe to separate them. Consider the canoes...
Consider a spring hung vertically from the ceiling. (a) When a 0.25kg block is attached to the spring, the spring is stretched 0.05m. What is the force constant of the spring? (b) What is the angular frequency for the simple harmonic motion of the block if you pull it down 5cm and release it? How does this compare to the angular frequency if you pull it down 10cm? (c) Taking upward to be positive, and the equilibrium position to be...
Scenario - Imagine you are building a computer from scratch, for yourself, a friend, or as a business investment or sell. Choose ONE type of person you are building this PC for (i.e., Gamer, Standard Home User, Home Business Owner, etc...).Write at least one paragraph (250-300 words) about the type of person you are building this computer for and what their needs are. Keep in mind the components you will need will determined by the needs of your customer (i.e....
1- A 300 ? mass is attached to
a solid 40 ?? long string the other end of which is secured to the
ceiling. The mass is given an initial speed which makes it swing
around a circular path in the horizontal plane without changing its
speed and without changing its height. The object completes 2
revolutions in 2 seconds.
A) What is the magnitude of the angular velocity of this
circular motion? B) Find the tension in the string....
Imagine you have $10,000 that you want to invest and you want to invest in some bonds. *You would be looking at the coupon rate (which is the interest rate that it will pay) since you want to get the highest return on your investment *You would also be looking at the risk rating to make sure it is not too risky or you might lose your money if the company gets into trouble financially. choose any company Example Microsoft...
A block of mass M = 1.1 kg is attached to a string which is wrapped around a pulley. As the block accelerates due to gravity the pulley rotates clockwise. The pulley can be thought of as a thin cylinder of mass m = 0.5 kg and radius r = 0.26 m. Consider positive to be the block moving down and the pulley rotating clockwise. What is the downwards acceleration of the block? What is the angular acceleration of the...
An object of mass, mi, is placed on a rough table and connected to a string which passes under a pulley then over a pulley and then is fastened to a hanging mass, m2. Assuming mi is stationary, how would you measure the coefficient of friction on mi? (That is calculate a formula for mu s as a function of m1 and m2) If the mass of m2 is increased until mi accelerates with acceleration a. What is the coefficient...
Imagine you are the HR executive of your organization (or any organization you are familiar with) and are responsible for aligning the performance management system to the strategic plan. How would you ensure that your employees’ goals are aligned to the mission and vision statements of your organization? Why will job analysis and developing suitable job descriptions be helpful? What would you do to gain employee support for your new performance management system? Embed course material concepts, principles, and theories,...
