Mr Gaglardi finds a spring and notices that he can stretch the spring by 25 cm when applying a force of 350 N to it. He then attaches the spring to a wall as shown. He places a 10 kg box on a nearby hill and pushes it with a force of 125 N down parallel to the slope over a distance of 1.2 m. The box travels down the slope against friction, and then 6.0 m over level ground also against friction before compressing a spring and coming to rest. If the spring gets compressed by 95 cm, how high up the hill did the box start? 

What are the reading of accurancies

 Two person are pulling a box on the three dimensional plane. If one person is pulling with the force of (20, 15, 10) N and the other person is pulling with a force of (13, -15, 25) N what is the resultant force acting on the box by these people.

In the Bainbridge mass spectrometer, the magnetic-field magnitude in the velocity selector is 0.650 T, and ions having a speed of 1.82 x 10 m/s pass through undeflected (a) What is the electric-field magnitude in the velocity selector? (b) If the separation of the plates is 5.20 mm, what is the potential difference between plates P and P"?

Show that the wavefunction Ψ(x) = N sin kx + iN cos kx is an eigen function of the momentum operator and determine its eigen value.
