Two blocks are on a frictionless surface. One block is at rest and the other collides with it at 25 m/s in the +x-direction. Both blocks have the same mass. The first block flies off at +45-degrees to the +x-axis and the other flies off at -45-degrees to the +x-axis.
What is the magnitude of the velocity of the two pucks? Assume that this is an elastic collision.
Draw a diagram to support your answer.

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...

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.
What is the final speed uf of...

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.
