A70 kg hockey player traveling at 6 m/s collides directly with a 76 kg player traveling at -5.4 m/s. which way do they go after the collision and what is their velocity after the collision? (assume that the players stick together after colliding).

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
