A billiard ball A moving at a speed of 2.4 m / s bumps into a
billiard ball B of the same mass, which
are at rest. After the impact, A moves at a speed of 1.4 m / s in a
direction that forms the angle 50 ◦
with A's original direction of movement. Determine the magnitude
and direction of B's velocity vector by
the impact. (Answer 1.8 m / s; 36 ◦)

of θ′A = 30.0∘ with a speed v′A = 2.10 m/s, and ball B moves with a
speed v′B at an angle of θ′B to original direction of motion of
ball A.

One billiard ball is shot east at 1.8 m/s . A second, identical
billiard ball is shot west at 1.1 m/s . The balls have a glancing
collision, not a head-on collision, deflecting the second ball by
90∘ and sending it north at 1.49 m/s .

A billiard ball is shot east at 2.80 m/s. A second, identical
billiard ball is shot west at 1.20 m/s. The balls has a glancing
collision, not a head-on-collision, deflecting the second ball by
90° and sending it north at 1.55 m/s. What is the angle that the
velocity of the first ball makes after the collision, with respect
to the east direction?

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10
m/s when it collides inelastically with a cup, mass m2 = 0.9 kg,
that is initially at rest. After the collision the system
(ball+cup) moves straight upwards without rotating. This collision
occurs on Earth, and the local gravitational field points down with
g = 9.8 m/s2 .
