a meter stick is held vertically with one end on thefloor andis then allowed to fall. find the speed of theother end when itmakes a 45 degree angle with the floor, assumingthat the end on thefloor does not slip. an alpha particle, m=4 collides elastically with acalciumatom, m=20, at rest. the initial velocity of thealphaparticle is Vi m/s. after collision the alpha particle hasavelocity 10i-5j m/s. is the velocity os the calcium atomaftercollision is vxi=vyj. find all the unknowns in theproblem.
