Question

Two 78.5-kg hockey players skating at 5.22 m/s collide and stick together.

If the angle between their initial directions was 105 ∘, what is their speed after the collision?

vf=?

Answer #1

Part A
Two 78.5-kg hockey players skating at 5.97 m/scollide and stick
together.I
f the angle between their initial directions was 140 ∘, what is
their speed after the collision? vf= m/s
Part B
A 0.30-kg croquet ball is initially at rest on the grass. When
the ball is struck by a mallet, the average force exerted on it is
260 N.
If the ball's speed after being struck is 5.1 m/s, for what
amount of time was the mallet...

2 air carts collide and stick together. cart one is M1
= 0.755 kg and initial speed of 0.435 m/s the cart to right is
initially at rest with mass m2= 0.300kg.
a.find the velocity of the center of mass before the carts Collide
and stick together
b. find the velocity of the center of mass after the carts Collide
and stick together
c. find the kinetic energy of the system before and after the
Collision

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.

Two cars, both of mass m, collide and stick together. Prior to
the collision, one car had been traveling north at speed 3v, while
the second was traveling at speed 2v at an angle ? south of east
(as indicated in the figure). After the collision, the two-car
system travels at speed vfinal at an angle ? east of north. (Figure
1) Find the speed vfinal of the joined cars after the collision.
Express your answer in terms of v...

An 80-kg man is skating north and accidentally collides with a
20-kg boy skating east. The two travel together after the collision
at 2.5 m/s at an angle of 60o north of east. What was the speed of
the boy before the collision?

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 large truck (mass 2,589 kg and speed 8.1 m/s) and a small car
(mass 1,166 kg and speed 23.8 m/s) going in opposite directions
collide head on. After the collision the two vehicles stick
together. Calculate their speed immediately after the
collision.

Two pieces of clay are moving directly toward each other. When
they collide, they stick together and move as one piece. One piece
has a mass of 324 grams and is moving to the right at a speed of
1.15 m/s. The other piece has mass 625 grams and is moving to the
left at a speed of 0.87 m/s. What fraction of the total initial
kinetic energy is lost during the collision? In other words what is
(KE?i???KE?f???? )/...

An Escort and a Camaro traveling at right angles collide and
stick together. The Escort has a mass of 1100 kg and a speed of 25
km/h in the positive x direction before the collision. The Camaro
has a mass of 1600 kg and was traveling in the positive y
direction. After the collision, the two move off at an angle of 49
o to the x axis. What was the speed of the Camaro?(in km/h)
