Question

Two hockey players hit each other on the ice. Player 1 is of mass 110 kg and is moving 70 East of South at 8 m/s. Player 2 is of mass 140 kg and is moving 50 North of West at 12 m/s. They collide and stick together. Sketch the situation. (a) Find the velocity of the vehicles after the collision. (b) Find the impulse on car1 during the collision. (c) Which car experiences the larger change in the magnitude of its momentum? Explain.

Answer #1

Two hockey players hit each other on the ice. Player 1 is of
mass 110 kg and is moving 70 degrees East of South at
8 m/s. Player 2 is of mass 140 kg and is moving 50 degrees North of
West at 12 m/s. They collide and stick together.
Sketch the situation.
(a) Find the velocity of the vehicles after the collision.
(b) Find the impulse on car1 during the collision.
(c) Which car experiences the larger change in...

In a game a few years ago, two football players crash into each
other during a tackle. The first player (mass 115 kg) is traveling
at 5.78 m/s, at an angle of 49.4 degrees south of east. The second
player (mass 98.0 kg) is traveling at 7.94 m/s, at an angle of 40.4
degrees north of east. The two players then collide, and stick
together right after the collision. Define north as positive y and
east as positive x.
A....

Object A (mass 10.0 kg) is moving due east with a velocity of
v⃑A0 = 8.00 m s EAST. Object B (mass 18.0 kg) is moving due north
with a velocity of v⃑B0 = 5.00 m s NORTH. They collide and stick
together. Find the magnitude and direction (in terms of an angle)
of the two-object system following 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?
N
Tries 0/2
What is the friction force exerted on the puck due to the
ice?
N
Tries 0/2
What is the magnitude of the acceleration of the puck due...

TWO SEPERATE QUESTIONS, thank you
question 1. Soccer player one has a mass of 45 kg and moves it
to the right with a speed of 1.4 m/s. Soccer player two has a mass
of 32 kg and moves to the left with a speed of 2.1 m/s.
What is the magnitude of the total momentum of the two
players?
question 2. A young hockey player stands at rest on the ice
holding a 1.1-kg helmet. The player tosses the...

Can you solve it please
Question 1:
A. A m1 = 80 kg ice skater moving at 50.4 km/h due North crashes
into a stationary skater of equal mass. After the collision, the
two skaters move as one body at 6 m/s due North. If the collision
lasts for 2.0 milliseconds, use the impulse – momentum theorem to
find: i. The impulse delivered to the m1 skater due to the
collision. ii. The magnitude of the average force exerted
on...

Two cars collide at an intersection. Car A, with a mass of 2000
kg, is going from west to east, while car of mass 1500 kg, is going
from north to south at 15 m/s. As a result, the two cars become
enmeshed and move as one. As an expert witness, you inspect the
scene and determine that, after the collision, the enmeshed cars
moved at an angle of 52∘ south of east from the point of impact.

Two cars collide at an intersection. Car A, with a mass of 2000
kg , is going from west to east, while car B , of mass 1400 kg , is
going from north to south at 17.0 m/s . As a result of this
collision, the two cars become enmeshed and move as one afterward.
In your role as an expert witness, you inspect the scene and
determine that, after the collision, the enmeshed cars moved at an
angle...

Object A is moving due east, while object B is moving due north.
They collide and stick together in a completely inelastic
collision. Momentum is conserved. Object A has a mass of mA = 16.0
kg and an initial velocity of v0A = 7.95 m/s, due east. Object B,
however, has a mass of mB = 30.5 kg and an initial velocity of v0B
= 4.85 m/s, due north. Find the magnitude of the final velocity of
the two-object system...

Students in question are in the back of a 3200 kg moving truck
travelling east at 50 km/h. The students intend on ramming the
truck with their 2000 kg vehicle to force it to a stop. As the
moving truck moves through a nice open parking lot, they travel at
80 km/h directly southwest (50 degrees south of west) and collide
with the moving truck. Both vehicles become stuck together and move
off as one after the collision. Treat east...
