149150 Ball $\mathrm{A}$ of mass $50 \mathrm{gm}$ an speed $10 \mathrm{~m} / \mathrm{s}$ collides with other ball $B$ of mass $10 \mathrm{gm}$ and speed 15 $\mathbf{m} / \mathbf{s}$ travelling in opposite direction with each other. Determine the final speed of ball $B$, if the coefficient of restitution is $\frac{2}{5}$.
149152 A ball is released from a height $h$. It hits the floor below and keeps bouncing repeatedly until it comes to rest. If the coefficient of restitution of the head-on collision between the ball and the floor is $e(e>>1)$, the total distance covered by the ball (vertically) from the point of its release to its rest position is given by

Two small particles of equal masses start moving in opposite directions from a point $A$ in a horizontal circular orbit. Their tangential velocities are $\mathrm{v}$ and $2 \mathrm{v}$ respectively, as shown in the figure. Between collisions, the particles move with constant speeds. After making how many elastic collisions, other than that at $A$, these two particles will again reach the point A?
