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...

frame?

A block with mass m1 = 0.450 kg is
released from rest on a frictionless track at a distance
h1 = 2.25 m above the top of a table.
It then collides elastically with an object having mass
m2 = 0.900 kg that is initially at
rest on the table, as shown in the figure below.
(a) Determine the velocities of the two objects just after the
collision. (Assume the positive direction is to the right. Indicate
the direction with...

Block 2 with mass m2=5.0 kg is at rest on a
frictionless surface and connected to a spring constant k=64.0 N/m.
The other end of the spring is connected to a wall, and the spring
is initially at its equilibrium (unstretched) position. Block 1
with mass m1=10.0 is initially traveling with speed
v1=4.0 m/s and collides with block 2. The collision is
instantaneous, and the blocks stick together after the collision.
Find the speed of the blocks immediately after the...

A block with a mass m1=2.3kg is sliding along a frictionless
surface with a velocity of 7.3m/s. It collides inelastically with
mass m2=1.7kg and the two blocks stick together. They then slide
down a frictionless incline with a Height 95cm. How fast are they
going when they reach the bottom of the incline?
Part B. If the coefficient of kinetic friction, uk is 0.15 along
the surface at the bottom of the ramp. What distance will the
blocks side before...

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...
