Question

two
balls of clay suffer a headon (1 - D) ) collision and stick
together Ball has a mass of 200 g and initially moving with a
velocity of 45 cm / s to the right has mass of 600 g and is
initially moving at 25 cm / s to the leftWhat their final velocity
in cm/s?

Answer #1

Law on conservation of momentum,

Suffix 1 is used for Ball 1 ; of mass, m1 = 200g and Intial velocity, u1 = 45 cm/s

Suffix 2 is used for Ball 2 ; of mass, m2 = 600g and Intial velocity, u2 = 25 cm/s

Since both balls sticks after collision,

Final velocity,

Substituting,

Two identical balls, a and b, collide and stick together. The
balls, which have a mass of 2kg eac, were initially moving towards
each other. b ball A had a speed of 5m/s and ball B had a speed of
3m/s just before a collision. What is the magnitude of the change
of Ball As momentum produced by the collision

Two balls of clay are shot at each other with an initial angle
of 110 degrees between them. One ball has a mass of 30 g and a
speed of 1.5 m/s, and the other ball has a mass of 40 g and a speed
of 1.2 m/s. When the balls collide, they stick together. What is
the velocity (speed and direction) of the 70-g ball after the
collision?

Two pieces of clay are moving directly toward each other. When
they collide, they stick together and move as one piece. One piece
having mass 300 300 g is moving to the right at a speed of 1 1 m/s.
The other piece has mass 600 600 g and is moving to the left at a
speed of 0.75 0.75 m/s.
a. Use momentum conservation to determine the velocity of the
combined clay piece after they collide. (Note: you can...

Two frictionless carts collide and stick together in a perfectly
inelastic collision, due to a magnetic or mechanical coupling, on a
one-dimensional track. Cart 1 has mass 200 grams and an initial
velocity of 2 m/s. Cart 2 has mass 900 g, and is initially
stationary. What is the velocity of the two carts together after
the collision?

Two pieces of clay are moving directly toward each other. When
they collide, they stick together and move as one piece. One piece
has a mass of 332 grams and is moving to the right at a speed of
1.16 m/s. The other piece has mass 606 grams and is moving to the
left at a speed of 0.934 m/s.
What fraction of the total initial kinetic energy is lost during
the collision? In other words what is (KEi -...

Two rubber balls undergo an elastic collision. Ball 1 has a mass
of 10 kg and an initial velocity of 5 m/s in the positive x
direction. Ball 2 has a mass of 10 kg and is
stationary. What is the final velocity of the two
balls, v1f, and v2f?

Two playful birds collide when they are at the top of their own
trajectories and stick together, stay tight thereafter. The first
bird is a strong beast of mass m1 = 300 g initially moving east
with a velocity of v1 = 25 cm/s , while the second bird is a frail
creature of mass m2 = 190 g initially moving west with a velocity
of v2 = 60 cm/s
a)Find the kinetic energy change due to the collision?

1.Two objects collide and stick together. The
collision [must be, may or may not be, cannot be] elastic.
2.Two objects collide and do not stick together. The collision
[must be, may or may not be, cannot be] elastic.
3.A moving object collides with an equal mass object initially at
rest. The first object stops after the collision. The collision
[must be, may or may not be, cannot be] elastic.
4. A moving object collides with another object of greater mass...

Collision Between Ball and Stick
On a frictionless table, a 0.62 kg glob of clay strikes
a uniform 1.12 kg bar perpendicularly at a point 0.21
m from the center of the bar and sticks to it. If the bar
is 1.34 m long and the clay is moving at 7.50
m/s before striking the bar, what is the final
speed of the center of mass?
2.67 m/s

Two carts on a friction free air track make a head-on collision
as shown. If the carts stick together on collision, what will their
final velocity (note signs) be? The car moving right has a speed of
30cm/s and a mass of 2M, the car moving to the left has a speed of
"-"40 cm/s with a mass of 1M
+33 cm/s+6.7 cm/s -6.7 cm/s+34
cm/s-33 cm/s
