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.
What is the final speed uf of block 1?
What is the final speed vf of block 2?

Two wooden blocks, M1 and M2 are sliding in the same direction at the same speed on a frictionless horizontal surface. Let M1=M2= 3kg and assume their speed is 2 m/s. A third block of mass m = 1 kg is also sliding in the same direction at a speed of 10 m/s, and it collides with the trailing 3 kg block. The third block is covered with a sticky, gooey substance, so it sticks to the trailing block. This...
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.] . Object A of mass M is initially at rest on a flat,...
