    Head-on elastic collision between two masses

    i use two equation v1= (m1-m2)*u1/(m1+m2) and v2= (2m1)*u1/(m1+m2). i substitute m1 = 1 and m2 = x. and then substitute in the ke equation. but i just cannot get the value for x

    Head-on elastic collision between two masses

    I have use the equation v1=(m1-m2)*u1/(m1+m2) and v2=(2m1)*u1/(m1+m2) then i substitute v1 and v2 into the ke equation. i also substitute m1 = 1 and m2 = x. i did not get the result i want

    Head-on elastic collision between two masses

    in a head-on elastic collision between two masses, one of which is stationary, a experimenter would like the incident mass to lose quarter of its kinetic energy in the collision. What must be the ratio of the masses of the two objects for this to be the case?

    Kinetic Energy Loss in Head-On Elastic Collision: Mass Ratios

    in a head-on elastic collision between two masses, one of which is stationary, a experimenter would like the incident mass to lose quarter of its kinetic energy in the collision. What must be the ratio of the masses of the two objects for this to be the case?
