Car A is traveling at 25 m/s. It experiences an inelastic collision after hitting a brick wall. Car B is traveling at 25 m/s. It experiences an elastic collision with a return
velocity of 6 m/s.
Compare the elastic collision of Car A to the inelastic collision of Car B. Both cars
have the same mass of 1500 kg. What is the difference (subtract the two) of
momentum between Car A and Car B.

What is friction? how does it affect the motion of an object?

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?
