    1. The problem statement, all variables and given/known data

    An object has a kinetic energy of 293 J and a momentum of magnitude 26.7 kg·m/s. Find the speed and the mass of the object.

    I don't know what equations I need...I know K=1/2mv^2 and P=Fv but I dont know how to relate them

    Since you know the formulas, just equate them. You will have two equations with two unknowns to solve simultaneously.
