Problem

Equal net forces act on two different blocks

A

and

B

of masses

m

and

4m

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

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

b. Their speeds are in the ratio

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

c. Work done on the blocks are in the ratio

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

d. All of the above
