The kinetic energies of two similar cars A and B are 100J and 225 J respectively. On applying breaks, car A stops after 1000 m and car B stops after 1500 m. If \(\text{F}_\text{A}\) and \(\text{F}_\text{B}\) are the forces applied by the breaks on cars A and B, respectively, then the ratio \(\text{F}_\text{A}\,/ \,\text{F}_\text{B}\) is
