A photograph shows a 0.3 kg bat traveling at 55 m/s just before it strikes a 0.05 kg
ball at rest on a tee. After the collision, the bat travels in the same direction at 42 m/s.
What is the speed of the ball just after impact?

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?
