A jet of mass 4,277 kg lands on an airstrip, stopping after a distance of 727 m and has an initial landing speed of 29 m/s.
What is the work done, in Joules, by non-conservative forces to stop the jet?
does this argumentive essay look good? it is about euthanasia (the right to die)
The argument I have picked is Euthanasia. An argument against the right to die. I don't see how my case proves against undoing attention. I do not draw any conclusion on the argument. The... more

1.(a) How much work is done to move a 1.80 X 103-kg Chevrolet Tahoe from rest to 35.2 m/s on a level road?(b) If this takes place over a distance of 251 m, what is the average net force applied to... more
What is the answer?
1. a worker pushes in 50.0 kg box on a level floor at constamt velocity and moves a distance of 10.0 m. If a person pushes it with a force of 850N, what must be the magnitude and the direction of... more
Work done by the Magnetic Force?
The magnetic part of the Lorentz force acts perpendicular to the charge's velocity, and consequently does zero work on it. Can we extrapolate this statement to say that such a nature of the force... more
How can tangential acceleration from a radial force be explained?
A mass is attached to a rope, and put into a circular motion. If I pull the string from the center, the tangential speed of the mass will increase (by conservation of angular momentum). I am... more
