Question

Block 1, of mass m1 = 12.3 kg , moves along a frictionless air track with speed v1 = 13.0 m/s . It collides with block 2, of mass m2 = 39.0 kg , which was initially at rest. The blocks stick together after the collision. Find the magnitude pi of the total initial momentum of the two-block system. Find vf, the magnitude of the final velocity of the two-block system. What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?

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...

Cart 1, with m1= 5.8 kg, is moving on a frictionless linear air
track at an initial speed of 1.8 m/s. It undergoes an elastic
collision with an initially stationary cart 2, with m2, an unknown
mass. After the collision, cart 1 continues in its original
direction at 0.7 m/s. 1) The horizontal component of the momentum
is conserved for cart 1. cart 2. the system of cart 1 and cart 2.
Momentum is not conserved for any of these...

In the figure, block 2 (mass 1.60 kg) is at rest on a
frictionless surface and touching the end of an unstretched spring
of spring constant 128 N/m. The other end of the spring is fixed to
a wall. Block 1 (mass 1.70 kg), traveling at speed v1 = 5.80 m/s,
collides with block 2, and the two blocks stick together. When the
blocks momentarily stop, by what distance is the spring
compressed?

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

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?
