Question

A hockey puck of mass 0.44 kg is shot west at 2.80 m/s strikes a second puck, initially at rest, of mass 0.55 kg. As a result of the collision, the first puck is deflected at an angle of 36° north of west, with a speed of 1.45 m/s. What is the speed of the second puck after the collision?

Answer #1

A hockey puck of mass 0.550 kg is moving to the right with a
speed of 5.80 m/s and has a head-on collision with a 1.00 kg puck
initially at rest. Assume a perfectly elastic collision.
What is the speed of the lighter puck after the collision?
What is the speed of the heavier puck after the collision?

Billiard ball A of mass mA = 0.125 kg moving with speed vA =
2.80 m/s strikes ball B, initially at rest, of mass mB = 0.138 kg .
As a result of the collision, ball A is deflected off at an angle
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.
(a) Solve these equations for...

A 0.495-kg hockey puck, moving east with a speed of 4.20 m/s ,
has a head-on collision with a 0.850-kg puck initially at rest.
a) Assuming a perfectly elastic collision, what will be the
speed (magnitude of the velocity) of each object after the
collision?

One billiard ball with a mass of 0.50 kg is shot east at 2.5
m/s. A second billiard ball with a mass of 0.25 kg is shot west at
2.0 m/s. The balls have a glancing collision, not a head-on
collision, deflecting the first ball by 90° and sending it north at
1.0 m/s.
What are the speed of the second ball after the collision?
What is the direction of the second ball after the collision?
Express your answer as...

A billiards ball of mass 0.2 kg strikes, another initially
stationary ball of the same mass. The first ball is deflected and
travels at an angle of 60o with its original direction. Its initial
speed was 5.0 m/s and after the collision, it is 3.0 m/s. What are
the magnitude and direction of velocity of the second ball after
collision?

A puck with a mass of 1.2 kg moves with a velocity of 5 m/s in
the x-direction. It collides with a 1.6 kg puck which is initally
stationary. After the collision, the second puck moves at a
velocity of 1.44 m/s at an angle of 33 degrees below the x
axis.
A) What is the angle of the first puck after the collision?
B)What is the velocity of the first puck after the
collision?

A billiard ball is shot west at 0.7 m/s. A second, identical
ball is shot east at 1.5 m/s. The balls have a glancing collision,
which deflects the first ball at 90 deg. and sending it north at
0.2 m/s. What is the speed of the other ball right after the
collision?

A hockey puck B rests on frictionless, level ice and is struck
by a second puck A, which was originally traveling at 40.0 m/s and
which is deflected 30.0◦from its original direction. Puck B
acquires a velocity at a 45.0◦to the original direction of A. The
pucks have the same mass. (a) What is the speed of each puck after
the collision?(b) What fraction of the original kinetic energy of
puck A dissipated during the collision? please show each step...

Billiard ball A of mass mA = 0.130 kg moving with speed vA =
2.65 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg .
As a result of the collision, ball A is deflected off at an angle
of 30.5 ∘ with a speed vA1 = 2.35 m/s .
C.) Solve for the speed, vB1, of ball B. Do not assume the
collision is elastic.
D.) Solve for the angle, θB, of ball B. Do...

One billiard ball is shot east at 2.5 m/s . A second, identical
billiard ball is shot west at 0.80 m/s . The balls have a glancing
collision, not a head-on collision, deflecting the second ball by
90∘ and sending it north at 1.34 m/s .
What is the speed of the first ball after the collision?
What is the direction of the first ball after the collision?
Give the direction as an angle south of east.
