One Piece V.2 Msn A Ball Of Mass M And Speed V Collides Head-on?

A ball of mass M and speed v collides head-on? - one piece v.2 msn

A ball of mass m and velocity v strikes the head
with a ball of mass 2m and speed v / 2, as shown
above. If both balls glued together, their speed
after collision
(A) 0
(B) V / 2
(C)
2
2 v
(D)
2
3 v
(E) 3 V / 2

Two objects of mass 0.2 kilograms, 0.1 kilograms,
, Each in parallel with the x-axis, as
above. The goal reached 0.2 kilograms
collides with the target of 0.1 kilograms. Immediately
after the collision, and the component of the
kg 0,2 is the subject of 1 m / s upward.
What is the Y component of the velocity
0.1 kilograms object immediately after the collision?
(A) 2 m / s downward
(B) 0.5 m / s downward
(C) 0 m / s
(D) 0.5 m / s upward
(E) 2 m / s upward

A stationary object explodes in burglary
three pieces of the masses m, m, and 3M. Both
Pieces of mass m is moving at right angles
the other with the same degree of
mV pulse, as in the picture shown above.
What are the magnitude and direction
Speed3M has a body part?
