Question

Two identical pucks collide on an air hockey table. One puck was
originally at rest. If the incoming puck has a velocity of 7.10 m/s
along the +x-axis and scatters to an angle of 36.0° above the
+x-axis, what is the velocity (magnitude and direction) of the
second puck? (You may use the result that θ_{1} −
θ_{2} = 90° for elastic collisions of objects that have
identical masses.)

Velocity (magnitude) =

Velocity (direction) = below +x-axis

What is the kinetic energy before and after the collision if the mass of each puck is 0.15 kg? (The collision is elastic.)

Kinetic energy before collision =

Answer #1

Two identical pucks collide on an air hockey table. One puck was
originally at rest. If the incoming puck has a velocity of 6.50 m/s
along the +x-axis and scatters to an angle of 32.0° above the
+x-axis.
A) What is the velocity (magnitude and direction) of the second
puck? (You may use the result that θ1 − θ2 = 90° for elastic
collisions of objects that have identical masses.)
Velocity (magnitude) = _______ Velocity (direction) = ________

Two hockey pucks of the same mass 0.5kg elastically collide on a
frictionless air hockey table. Incoming puck A has a velocity of
6m/s and scatters at an angle of 50°. Puck B is initially at rest
and scatters 40° the other way. Solve for the speed of Puck A after
the collision.

The drawing shows a collision between two pucks on an air-hockey
table. Puck A has a mass of 0.20 kg and is moving along the
x axis with a velocity of 6.60 m/s. It makes a collision
with puck B, which has a mass of 0.40 kg and is initially at rest.
After the collision, the two pucks fly apart with angles as shown
in the drawing (α = 62° and β = 40°). Find the final speed of puck...

A 70.0-kg ice hockey goalie, originally at rest, has a 0.170-kg
hockey puck slapped at him at a velocity of 35.5 m/s. Suppose the
goalie and the puck have an elastic collision, and the puck is
reflected back in the direction from which it came. What would the
final velocities of the goalie and the puck be in this case? Assume
that the collision is completely elastic.

7. A 77.0 kg ice hockey goalie, originally at rest, catches a
0.150 kg hockey puck slapped at him at a velocity of 34.0 m/s.
Suppose the goalie and the ice puck have an elastic collision and
the puck is reflected back in the direction from which it came.
What would their final velocities (in m/s) be in this case? (Assume
the original direction of the ice puck toward the goalie is in the
positive direction. Indicate the direction with...

A 81.0-kg ice hockey goalie, originally at rest, catches a
0.150-kg hockey puck slapped at him at a velocity of 28.0 m/s.
Suppose the goalie and the ice puck have an elastic collision and
the puck is reflected back in the direction from which it came.
What is the final velocity of the goalie?

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...

a) A 70.0-kg ice hockey goalie, originally at rest, catches a
0.150-kg hockey puck slapped at him at a velocity of 35.0 m/ s.
Suppose the goalie and the ice puck have an elastic collision and
the puck is reflected back in the direction from which it came.
What would their final velocities be in this case?
b) Suppose instead that the goalie caught the puck. What is the
velocity of the goalie/puck system after the catch?

Two identical pucks are on an air table. Puck A has an initial
velocity of 2.5 m/s in the positive x-direction. Puck B is
at rest. Puck A collides elastically with puck B and A moves off at
1.4 m/s at an angle of +60

A 70.0-kg ice hockey defender, originally at rest near the goal,
has a 0.170-kg hockey puck slapped at him at a velocity of 33.5
m/s. Suppose the defender and the puck have an elastic collision,
and the puck is reflected back in the direction from which it came.
What would the final velocities of the defender and the puck be in
this case? Assume that the collision is completely elastic.
