An Electron is incident on a nitrogen atom (mass=7.37x10-25kg). The electrons initial velocity is 4x104 m/s. The nitrogen atom is at rest. If The electron deflects backwards at an angle of 35 degrees below the horizontal, and at 3.7x104m/s what is the velocity and direction of the nitrogen atom? (mass of an electron is 9.11x10-31kg)

A water jet has an actual velocity of 88.256 m/s and a mass flow rate of 17.745 kg/s. This jet strikes an upward curved vane moving at 20 ms–1 in a horizontal direction away from the jet, which deflects the water through an angle of 115º. The impact is shockless. Calculate: (i) the magnitude and direction of the velocity of the fluid leaving the vane; (ii) the thrust on the vane in a horizontal direction; (iii) the thrust on the...

An object of mass M moving at speed v0 has a direct elastic collision with a second object of mass m that is at rest. Using the energy and momentum conservation principles, it can be shown that the final velocity of the object of mass M is v=(M−m)v0/(M+m). Part A Using this result, determine the final velocity of an alpha particle following a head-on collision with an electron at rest. The alpha particle's velocity before the collision is 0.010c; malpha=6.6×10−27kg;...
