so then to find the electric field you use E= (kq1q2)/r where q1 would be the charge on the lead and q2 would be the charge on the alpha particle r would be the minimum distance. Then e would be the potential energy which would then be converted to kinetic energy as the alpha particle moves...

Homework Statement An a particle of mass 6.6 x 10-27 kg came closest to an atom of lead with a distance of 4.8 x 10-14 m. At what velocity will the a particle rebound directly away if the collision is totally elastic? Mass of the Alpha Particle - 6.6 x 10^-27 kg Alpha particles are...

and they need to equal the total of the initial vector.

Because my original vector is in only one dimension let's say east then the north of one vector has to equal the south of the other vector. Correct? Plug in the numbers and solve?

A 0.40-kg cue ball makes a glancing blow to a stationary 0.30-kg billiard ball so that the cue ball deflects with a speed of 1.2 m/s at an angle of 30.0º from its original path. Calculate the original speed of the cue ball if the billiard ball ends up traveling at 1.5 m/s. from its original...
