Block 1, of mass m1, moves across a frictionless surface with speed
ui . It collides elastically with block 2, of mass m2, which is at
rest (vi = 0). After the collision, block 1 moves with speed uf ,
while block 2 moves with speed vf . Assume that m1 > m2, so that
after the collision, the two objects move off in the direction of
the first object before the collision.

Block 1, of mass m1,
moves across a frictionless surface with speed ui. It collides
elastically with block 2, of mass m2, which is at rest (vi=0).
(Figure 1) After the collision, block 1 moves with speed uf, while
block 2 moves with speed vf. Assume that m1>m2, so that after
the collision, the two objects move off in the direction of the
first object before the collision.Part

Block A of mass mA is moving horizontally with speed Va along a frictionless surface
Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...

Object A of mass M is initially at rest on a flat, smooth
frictionless surface. Object B, which has twice the mass of A, is
traveling with speed V before it collides elastically with A.
Immediately after the collision, both objects move off at angles
(theta)>0 with respect to the original direction of B. Calculate
the value of the angle.
[Hint: Note that the collision is elastic.] .

A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to move off at an angle θ′2=45∘. The neutron's initial speed is 6.0×105 m/s . Determine the angle of the neutron, θ′1, after the collision. Determine the speeds of the two particles, v′n and v′He, after the collision
