Two spheres, fastened to "pucks", are riding on the frictionless air track. Sphere 1 is charged with 1 nC, and sphere 2 is charged with 3 nC. Both objects have the equal mass. 1 nC is equal to 1 × 10-9 C.
Q2. A train is travelling up a 5 degree incline at a speed of 2.2 m/s while the last car breaks free and begins to coast without friction. a) How long does it take for the last car to come to rest momentarily? b) How far did last car travel before momentarily coming to rest?
