    Can anybody explain how to startup the questions? Thank you! :surprised

    For the first question : use conservation of linear momentum and conservation of energy. That's all you'll need to do.

    Be sure that you apply momentum-conservation in both the x and y direction of the frame of reference.

    The formula they gave looks weird...That [itex] \vartheta_{2} [/itex] is written as a function of [itex] \vartheta_{1} [/itex] & [itex] \cos\vartheta_{2} [/itex] :bugeye:

    Since the problem reminds somehow of the classical HS theory of Compton effect,i assume that [itex]\vartheta_{2} [/itex] can be found exactly...

    I AGREE (hey that feels strange :rofl: ). The formula i get has a v1' and a cosine of theta_1, instead of v1 * cos(theta2). It seems quite stupid to me that we'd set up a formula for theta 2 that actually contains the theta2
