Question

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?

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 67.0 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 the...

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.

A 105 kg ice hockey goalie, originally at rest, catches a 0.150
kg hockey puck slapped at him at a velocity of 27.7 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. Take the
puck's initial moving direction as positive.
(a) What is the puck's final velocity (in m/s)? (keep 2 decimal
places)
(b) What is the goalie's final velocity (in m/s)? (keep 3...

A
young 43-kg ice hockie goalie, originally at rest, catches a
0.145-kg hockey puck slapped at him at a speed of 34.5 m/s. In this
problem, take the original direction of the puck as positive.
Part A) 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 the final velocity of the puck, in meters
per second, be in this case?

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 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.
Note: To practice the center-of-mass frame content, tackle this
problem...

A 70-kg hockey player, originally at rest, hits a 0.15-kg hockey
puck slapped at him at a velocity of 35 m/s. Following the hit the
ice puck reflected back at 34.85 m/s in the direction from which it
came. Ignore friction. Determine the final velocity of the hockey
player.
Select one:
a. -5.25 m/s
b. 5.25 m/s
c. 0 m/s
d. 0.1497 m/s

A 97.0 kg ice hockey player hits a 0.150 kg puck, giving the
puck a velocity of 49.5 m/s. If both are initially at rest and if
the ice is frictionless, how far (in m) does the player recoil in
the time it takes the puck to reach the goal 17.5 m away?
