A charged particle (mass 5.0 milligrams) was travelling in a vacuum at 0.4 kmfs at 30 degrees North of East at t: 0 when it entered a uniform electric field which exerted a constant force of Si mN East on the particle for 7.1 ms. At t: 7.1 ms. the particle was 2.7'l 653 m East and 'l.42 m North ofwhere it was at t: 0. During the 7.1 ms interval, the impulse exerted on the particle was N s East and the work done was J. At t: 7.'l ms, the momentum ofthe particle was kg mx's at degrees North of East. and the kinetic energy was J. (Note: you can give your answers in scientific notation using this form: 4e3 (which means 4 X it) to the power 3) Also: remember that the SI unit of mass is kg
