Find the work W done by the 15-newton force. B>D=A>C. Rank the joggers in order of decreasing kinetic energy. Indicate ties where appropriate.Find the work W done by the 18-newton force. Concepts and reason The concept of work done and force is required to solve the problem. The work done by the applied force is calculated by taking the dot product of force and displacement. Fundamentals Work is done whenever force acting on an object causes it to displace in the direction of force. The work done by a constant force is determined by10/6/2015 Assignment 9 5/23 Correct Part K Find the work done by the 15newton force. Use two significant figures in your answer.

Find the work W done by the 18-newton force. Posted 3 months ago The work done in moving an object through a displacement of d meters is given by W = Fd cos θ, where θ is the angle between the displacement and the force F exerted.A box of mass m is sliding down a frictionless plane that is inclined at an angle ϕ above the horizontal, as shown in the figure (Figure 2). What is the work done on the box by the force due to gravity w, if the box moves a distance d? W=wdcosϕ W=wdcos(90−ϕ) W=0 None of theseWork Done on a Heavy Bucket Filled With Coal. Miners use machines to pull a heavy cable which is attached to a heavy bucket filled with coal. The cable is also heavy that's why the force exertedFind the work w w done by the 18 18 newton force. Work Done Due to a Force: The displacement of an object, the magnitude of the force, and the angle between the force and the displacement are used...

ANSWER Correct Part I Find the work done by the 30newton

Work done: W = F · d c o s θ The angle between two parallel vectors is 0 while the angle between antiparallel vectors is 180. The angle between the 12 N force and the direction of motion is 180°.2 Q2: In this problem, you will calculate work done on an object moving in a straight line.

Find the work W done by the 12-newton force.-1900 J. Find the work W done by the 15-newton force.-1800. In addition to a before-and-after pictorial representation, in energy problems it is often useful to draw energy bar charts, as the ones shown below. Taking the initial state of the system toI am having trouble with this question: if an object undergoes displacement while being acted upon by a force (or several forces), it is said that work is being done on the object. If the object is moving in a straight line and the displacement and the force are known, the work done by the force can be calculated as W = F*s Find the work W done by the 18-newton force.
