Two bodies of equal masses are moving with uniform velocities v and 2v.Find the ratio of their of heir kinetic energies?
Kinetic energy is equal to the mass of the object times the velocity squared (Ek=.5mv2). To obtain the ratio between the two objects, divide the first by the second (Ek1/Ek2). This is equivalent to .5m1v12/.5m2v22. Since the masses are equal, they cancel out and you are left with v12/v22. Next, as stated in the problem, the seceond velocity is twice as much as the first so plug that coefficient into the aforementioned equation. (1v12)/(2v22). Since the values of velocity (v) are equal in this problem, they can cancel out just as the masses did. Now, 12=1 and 22=4; so the ratio is 1/4.
The efficiency of a real machine?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
What is the ratio of kinetic energies between two particles of masses 1g and 4g moving with equal linear momentum?
GIven m1v1 = m2 v2 -----------------(1) Needed m1v12 / m2v22 = v1 / v2 But right from (1) v1 / v2 = m2 / m1 Given m1 = 1 g and m2 = 4 g So required ratio of KE = 4:1

How can you make the momentum of a marble and a basketball equal?
-- Measure the weight of the marble. -- While on the same planet, measure the weight of the basketball. Since both measurements were made on the same planet, the ratio of the weights is the same as the ratio of the masses. -- Divide the big weight by the small weight (Wb/Wm); call the answer ' R '. -- Start the basketball moving, and measure its speed; call the speed ' S '. -- Make the marble move at a speed of ( R times S ). Their momenta are now equal. Momentum = (mass) times (speed), and that product is now the same for both objects.
