A

and

B

of masses

m

and

4m

, respectively. For the same displacement, identify the correct statement. (1) Their kinetic energies are in the ratio

\frac{K_A}{K_B}=\frac{1}{4}

(2) Their speeds are in the ratio

\frac{v_A}{v_B}=\frac{1}{1}

(3) Work done on the blocks is in the ratio

\frac{W_A}{W_B}=\frac{1}{1}

(4) All of the above
