Question

Two balls moving with the same speed of *v* = 0.48 m/s
but in opposite directions undergo a head-on collision. Ball
*A* has mass *m _{A}* = 2.6 kg and is
traveling to the left, while ball

(a) Which ball has the larger momentum (in magnitude) before the collision?

Ball *A*

Ball *B*

Both balls have the same momentum (in magnitude) before the
collision

(b) Before the collision, the total momentum vector for the
system

points to the right.

points to the left.

is zero.

(c) During the collision,

the force ball *A* applies to ball *B* is larger
in magnitude than the force ball *B* applies to ball
*A*.

the force ball *A* applies to ball *B* is smaller
in magnitude than the force ball *B* applies to ball
*A*.

the force ball *A* applies to ball *B* has the
same magnitude as the force ball *B* applies to ball
*A*

(d) Which ball undergoes the larger change in momentum (in
magnitude) during the collision?

Ball *A*.

Ball *B*.

Both balls undergo the same change in momentum (in magnitude) during the collision.

(e) After the collision, the total momentum vector for the
system

points to the right.

points to the left.

is zero

(f) As a result of the collision, the two balls stick together. The
speed of the balls after the collision is

0.48 m/s (same as before the collision)

0.24 m/s (half the speed before the collision).

0.16 m/s (one-third the speed before the collision).

Thank you very much. Best of luck.

Two balls traveling in opposite directions collide head on.
Ball1 is traveling in the positive x
direction at a speed of v1 = 4.50
m/s and mass of m1 = 2.0
Kg. Ball2 is
traveling in the negative x direction at a speed
of v2 = -6.50 m/s and a mass of
m2 = 4.0 Kg.
a) If we assume that the two balls are made of
clay and become one mass during the collision what is their
combined final...

A truck of mass M and a car of mass m are moving along a level
roadway in opposite directions at the same velocity. The car and
the truck are involved in a head-on collision. Assume that neither
driver had time to apply the brakes before or during the collision.
Immediately after the collision the two vehicles are stuck to each
other, and the wheels are still rolling.
Part 1
During the collision, the force on the car due to...

A ball with mass M = 5 kg is moving with speed V=10 m/s and
collides with another ball with mass m = 2.5 kg which is initially
stationary. There is no other force such as gravity acting on the
two balls. After the collision, both balls move at angle θ=30
degrees relative to initial direction of motion of the ball with
mass M = 5 kg. a) What are the speeds of the two balls after the
collision? b)...

Two balls collide elastically. Ball A has a mass of 3.00 kg and
moves to the right at 2.00 m/s. Ball B has a mass of 1.29 kg, and
moves to the left, also at 2.00 m/s.The balls collide head-on. A)
Find the speed of Ball A after the collision. B) Find the speed of
Ball B after the collision. C) Find the impulse delivered to Ball A
during the collision. D) Find the impulse delivered to Ball B
during...

Mass m = 0.1 kg moves to the right with speed v = 0.48 m/s and
collides with an equal mass initially at rest. After this inelastic
collision the system retains a fraction = 0.88 of its original
kinetic energy. If the masses remain in contact for 0.01 secs while
colliding, what is the magnitude of the average force in N between
the masses during the collision? Hints: All motion is in 1D. Ignore
friction between the masses and the...

A 0.060 kg tennis ball, moving with a speed of 7.10 m/s has a
head-on collision with a 0.080 kg ball initially moving away from
it in the same direction at a speed of 3.40 m/s. Assuming a
perfectly elastic collision,
What is the velocity of the tennis ball after the collision?
(Take the initial direction of the balls as positive.) m/s
What is the velocity of the 0.080 kg ball after the collision?
m/s

A BMW of mass 2000 kg is traveling at 42 m/s. It approaches a
1000 kg Volkswagen going 25 m/s in the same direction and strikes
it in the rear. Neither driver applies the brakes. Ignore the
relatively small force on the cars due to the road and due to air
resistance. (a) If the collision slows the BMW down to 33 m/s, what
is the speed of the VW after the collision? (b) During the
collision, which car exerts...

A 1000-kg sports car is moving north at speed 15 m/s on a level
road when it collides with a 2000-kg truck driving east on the same
road at speed 10 m/s. The two vehicles remain locked moving
together after the collision at the origin of x-y plane. Assume
that the rolling friction is too small to be ignored.
A) explain what type of collision it is
B) indicate the vector momentum by showing its magnitude and the
(direction) angle...

Two balls with masses of m1 = 10 kg and m2 = 50 kg undergo an
elastic collision with the first ball traveling east with a
