Two clowns are launched from the same spring$-$loaded horizontal circus cannon with the spring compressed the same distance each time. Clown A has a $40-$ kg mass; clown B a $60-kg$ mass the relation between their speeds at the instant of launch $($i$.$e$.$ when they leave the spring$)$ is

$v_B=(\frac{3}{2})v_A.$

$v_B=V(\frac{3}{2})v_A.$

$v_A=V(\frac{3}{2})v_B.$

$V_A=(\frac{3}{2})v_B.$

$v_A=v_B.$
