The co-ordinates of a moving particle at any time 't' are given by x = $$\alpha $$t³ and y = βt³. The speed to the particle at time 't' is given by

$$3t\sqrt {{\alpha ^2} + {\beta ^2}} $$

$$3{t^2}\sqrt {{\alpha ^2} + {\beta ^2}} $$

$${t^2}\sqrt {{\alpha ^2} + {\beta ^2}} $$

$$\sqrt {{\alpha ^2} + {\beta ^2}} $$

From a building two balls A and B are thrown such that A is thrown upwards and B downwards ( both vertically with the same speed ). If v_A and v_B are their respective velocities on reaching the ground, then

$${v_B} > {v_A}$$

$${v_A} = {v_B}$$

$${v_A} > {v_B}$$

their velocities depend on their masses.
