Question

The inclined surfaces of two movable wedges of same mass M are smoothly conjugated with the horizontal plane as shown in figure. A washer of mass m slides down the left wedge from a height h. To what maximum height will the washer rise along the right wedge? Neglect friction.

$\frac{h}{(M + m)^{2}}$
$\frac{h M}{(M + m)^{2}}$
$h {(\frac{M}{M + m})}^{2}$
$h (\frac{M}{M + m})$

The correct answer is: $h open parentheses fraction numerator M over denominator M plus m end fraction close parentheses to the power of 2 end exponent$

In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius R/2, is coming down vertically and has a velocity = v0 when it simultaneously hits the two balls and itself comes to rest. Then, each of the two bigger balls will move after collision with a speed equal to
