Question

A 100-gram hockey puck is initially moving horizontally *to
the left* at a speed of 10 m/s, but is then slapped with a
hockey stick *to the right* and moves off with a speed of 20
m/s. If the collision time between the hockey stick and the puck is
*∆t* = 0.030 s, what is the average force of the hockey
stick on the puck, in Newtons?

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?

A hockey puck (mass = 3.5 kg) leaves the players stick (moving
to the left) with a speed of 28 m/s and slides on the ice before
coming to rest.
The coefficient of friction between the puck and the ice is
0.9.
What is the normal force on the puck?

A 160g hockey puck initially moving with a speed of 5.00 m/s
slides for 25.0 m across the ice sheet of a hockey rink before
coming to rest.
What is the acceleration of the puck as it moves?

1)
A crash test dummy with a mass of 65-kg is in a moving car going at
20 m/s, until it crashes into a wall. If the applied force was
measured at 1,750 N, how long (in seconds) did the collision last?
2) Consider two hockey pucks on frictionless ice: Puck A with
a mass 1.10 kg, and Puck B with a mass of 0.60 kg.
Puck A is initially moving to the right at 1.75 m/s towards
puck B,...

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?

A soft ball (m = 0.14 kg) moving horizontally to the right hits
a wall with a speed of 16.2 m/s. After the collision the ball
bounces back and moves horizontally to the left at a speed of 14.4
m/s. If the collision lasts for 0.0015 s, what is the magnitude of
the (average) force exerted on the ball by the wall?

On a frictionless, horizontal air table, puck A (with mass 0.250
kg ) is moving toward puck B (with mass 0.400 kg )
A -After the collision, puck A has a velocity of 0.150 m/s to
the left, and puck B has velocity 0.750 m/s to the right. What was
the speed of puck A before the collision?
B- If the two pucks collide and stick together with a final
velocity of 0.6000 m/s to the right, what was the...

During practice, a hockey player passes the puck to his coach
who is 6.5 m away as shown in the figure below.
The puck, which has a mass of 0.198 kg, was initially at rest.
The hockey player exerts a constant 46.9-N force as his stick
pushes the puck 0.17 m. Include only the puck in the system and
assume the friction between the ice and the puck is negligible.
(a) Draw a free-body diagram for the puck while it...

1. On a frictionless horizontal air table, puck A (with mass
0.252 kgkg ) is moving toward puck B (with mass 0.375 kgkg ), which
is initially at rest. After the collision, puck A has velocity
0.122 m/sm/s to the left, and puck B has velocity 0.651 m/sm/s to
the right.
Calculate ΔKΔKDeltaK, the change in the total kinetic energy of
the system that occurs during the collision.
