mass of height h=9.8 m. What is the kinetic energy K of the masses
when they reach the top of the hill.

K=655 J

The figure below shows a mass m1=5.2 kg moving with velocity
v1=47.6 m/s which collides with a mass m2=3.8 kg which is initially
at rest. The collision is completely inelastic and the masses slide

kinetic energy K of the masses when they reach the top of the
hill.
K=727 J
K=3879 J
K=2425 J

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a
completely inelastic collision with a stationary block of mass m2 =
0.500 kg . The blocks then move, stuck together, at speed v2. After
a short time, the two-block system collides inelastically with a
third block, of mass m3 = 2.60 kg , which is initially at rest. The
three blocks then move, stuck together, with speed v3. Assume that
the blocks slide without...

A particle of mass m1 = 1.32 kg with an
initial velocity v1 = 4.56 m/s
has a completely inelastic collision with a second particle of mass
m2 = 3.68 kg with an initial velocity
v2 = 3.06 m/s. What is the
velocity of the combined particles immediately after the collision?
(Express your answer in vector form.)

A ball of mass m1=0.250 kg and velocity v1=5.00 m/s
[E] collides head-on with a ball of mass m2=0.800 kg that is
initially at rest. No external forces act on the balls.
a. Show what is conserved through the appropriate formula if the
collision is elastic.
b. What are the velocities of the balls after the
collision?

A man of mass m1 = 64.5 kg is skating at v1 = 7.60 m/s behind
his wife of mass m2 = 53.0 kg, who is skating at v2 = 3.80 m/s.
Instead of passing her, he inadvertently collides with her. He
grabs her around the waist, and they maintain their balance.
(a) Sketch the problem with before-and-after diagrams,
representing the skaters as blocks.
(b) Is the collision best described as elastic, inelastic, or
perfectly inelastic? elastic inelastic perfectly inelastic...

A block of mass m1 = 2.6 kg initially moving
to the right with a speed of 4.5 m/s on a frictionless, horizontal
track collides with a spring attached to a second block of mass
m2 = 5.6 kg initially moving to the left with a
speed of 2.9m/s. The spring constant is 504N/m.
Now, What if m1 is initially moving at 3.4
m/s while m2 is initially at rest?
(a) Find the maximum spring compression in this case. x...

A block of mass m1 = 1.2 kg initially moving
to the right with a speed of 4.2 m/s on a frictionless, horizontal
track collides with a spring attached to a second block of mass
m2 = 2.8 kg initially moving to the left with a
speed of
1.0
m/s as shown in figure (a). The spring constant is 535N/m.
What if m1 is initially moving at 2.6 m/s
while m2 is initially at rest?(a) Find the
maximum spring compression...

An object of mass m1 approaches with velocity v1 another object
of mass m2, which is at rest, next to a spring having force
constant k. The spring is fixed to a wall and m2 can compress the
spring. This is one-dim horizontal collision without friction. We
consider two collision scenarios, one which is perfectly inelastic,
and the other which is elastic. (a) In the first collision case the
object m1 strikes m2 and sticks. Moving together, they compress the...

A block of mass m1 = 1.90 kg initially moving to the right with
a speed of 4.6 m/s on a frictionless, horizontal track collides
with a spring attached to a second block of mass m2 = 4.8 kg
initially moving to the left with a speed of 1.1 m/s.The spring
constant is 519 N/m.
What if m1 is initially moving at 3.4 m/s while m2 is initially
at rest? (a) Find the maximum spring compression in this case. x...

A block moving with speed vo = 10 m/s and mass m1 = 6 kg
collides with a block of mass m2 = 5 kg initially at rest. (Both
slide on a frictionless surface at all times.) Now the two blocks
collide with a third block initially at rest. What is the final
momentum of the system?
Question options:
A) 30 kg-m/s B) 60 kg-m/s C) 190 kg-m/s D) 250 kg-m/s E) 310
kg-m/s
