A block of mass 4m moves on a flat horizontal surface at speed
v, and strikes another block of mass m, that is attached via a
horizontal spring to another block of mass 2m. The two masses are
stationary. The spring constant is k. All collisions are
completely inelastic and there is no friction anywhere.
What is the velocity of the center of mass when the spring is ¼ the
way to max compression.

Mass m = 0.1 kg moves to the right with speed v = 0.54 m/s and
collides with an equal mass initially at rest. After this inelastic
collision the system retains a fraction = 0.9 of its original
kinetic energy. If the masses remain in contact for 0.01 secs while
colliding, what is the average force in N between the masses during
the collision? Hints: All motion is in 1D. Ignore friction between
the masses and the horizontal surface. You...

A block of mass m1 travels at a speed of v0 on a frictionless
horizontal surface when it comes upon a second block of mass m2
which is initially motionless. Block m2 has a massless spring with
spring constant k in front of it. a. Explain why the linear
momentum of the system of two blocks and spring is or is not
conserved during the collision. b. Explain why the mechanical
energy of the system of two blocks and spring...

a)An object of mass ?m rests on a horizontal frictionless
surface. A constant horizontal force of magnitude ?F is applied to
the object. This force produces an acceleration:
always
only if ?F is larger than the weight of the object
only while the object suddenly changes from rest to motion
only if ?F is increasing
choice A
b)Now let there be friction between the surface and the object.
If the object has a mass of 10 kg, and ??μs =...

A particle of mass m is constrained to lie along a frictionless,
horizontal plane subject to a force given by F (x) = −kx + kx^3/A^2
where k and A are positive constants. The particle is projected
from x = 0 to the right with initial kinetic energy T0. Find the
turning points of the motion and the condition the total energy of
the particle must satisfy if its motion is to exhibit turning
points.

collides and sticks to the end of a uniform rod of length L and

vertical plane. Find the angular speed right after the

A 0.990 kg block slides on a frictionless, horizontal surface
with a speed of 1.40 m/s. The block encounters an unstretched
spring with a force constant of 231 N/m. Before the block comes to
rest, the spring is compressed by 9.17 cm.
1) Suppose the force constant of the spring is doubled, but the
mass and speed of the block remain the same. By what multiplicative
factor do you expect the maximum compression of the spring to
change? Explain.
